Dementia Care Pathway-People with Learning Disability Essay

The Psychiatrist is responsible for making the decision with regards to diagnosis; they will be reliant on the information and assessments of other professionals to assist in this process. The Psychiatrist will then decide on the most appropriate treatment for treating. The key role of the community nurse is to maximise the health and wellbeing of an individual. Looking at the individual from a holistic perspective the nurse will promote good health with proactive strategies, minimise health risks through assessment and care planning. The primary goal of Occupational Therapy is to enable people to participate in the activities of everyday life. Occupational Therapists engage with clients using activities that are meaningful and purposeful to them to assess and treat the physical, psychological and social needs of the individual and their environment to enable them to reach or retain their optimum potential. OTs use a range of different assessment methods, looking at functional and cognitive skills, for activities of daily living, activity levels sensory needs and well-being. Physiotherapists are responsible for promoting mobility to the optimum level for as long as possible and then for assessing and providing additional support and mobility aids when necessary. Speech and Language Therapists working with individuals with learning disabilities who have developed dementia cover two main areas: Communication: The Speech and Language Therapist’s role is to assess the communication needs of the individual with dementia, identify means for supporting these, and advising carers and support workers regarding improved, or successful communication. Eating and Drinking: The role of the speech and language therapist is, in liaison with others, to assess the individual and advise regarding strategies to improve safety of eating, drinking and swallowing or to suggest strategies to support the maintenance of adequate oral intake. Clinical Psychologists can be involved in diagnosing dementia, often when the person’s difficulties are complex and the diagnosis unclear. Once a diagnosis has been made psychologists would intervene where there are problems such as challenging behaviour, depression and anxiety, or where there are issues to do with loss, illness and disability.

Origin of Science and the Crusade

But when we look at the history of the world Egyptian, Greeks, Roman, Persian, Mongolia, Saracen, British, Dutch, Portuguese, Chinese, Indian and any others had been the super power in different periods of the history. Yet when we talk anybody about a scientific Inventions and discoveries or major leap In the scientific development most tent to point their fingers towards the Europe if It Is before 18th century and towards the USA if it is after 1 9th century. This sort of behavior is deep down in our minds. But is this correct?If so, why the non-European nations were super power? For this I think we have to take a Journey in the history of Science from the early Egyptians. In this short article I would like to take an excursion bout the origins of science, where there the history had been littered with many manipulation and misconception. According to many in the world the science was begun by Greeks and was developed by the post renaissance Europe. As the same time all the great cu ltures like Persian, Egyptian, Chinese and Indian had no clue regarding the science.But when we look at the history of these civilizations we can understand how developed they were in the history. Egyptians were one of the early races before Greeks who were developed in the Science. They were well versed In anatomy (for art), astronomy and astrology, which ere inseparably linked in ancient Egypt, biology and veterinary medicine, chemistry, geography, geology, history, law, geometry, medicine, mineralogy, pedagogy(education), philosophy, physics, sociology and theology [1]. Irrigation scheme of Nile, tall standing pyramids and the mummies are some example of scientific feat of the Egyptians.Geometry was applied in the Egypt for tax purposes before the so called Euclid of Greece wrote the book of The Elements. Here comes another manipulation of History again in the form of Euclid. Many text books refer Euclid was a white male eventually from Greece and ivied in Alexandria around three century B. C. But no such person was alive on this mother earth. The author of this book is a black woman from Alexandria who lived around fifth century C. E. [2] From these arguments we can assure that the Greek were not the first one to begin the Science.Now let's consider the development of Science. If we consider the manipulated version of the science history, we get a wide blank span of time from the Greek civilization to the renaissance Europe. Where were the text and the sources of these scientific theorems and formulae? Were they 2 Origin of Science and the crusades I Mohamed Gammy Shifter_209110164 buried in the Mount Olympus? No. They were translated taken into custody by another civilization which have contributed to the many of the scientific development and not credited to it.Yes it was taken into the custody by Islamic Civilization. They hold these texts of Greek until the crusades [2]. The west claims that the Muslim merely translated the works of Greek and preserved it. They never did develop the ideas in the text. This argument is absurd. The Muslims practically ruled from the shore Atlantic Ocean to the boarders of China. And they Just preserved these texts which cost a fortune with the papyrus technology. Many books from Baghdad Library were destroyed by the invasion of Mongols over Jeremiah on 13th century C. E.But the contributions of All Bin Sins (Vicuà ±a) – whose â€Å"The Book of Healing† was text book for medicine in many medieval universities[3], Legalize Bin al Haitian, Jabber bin Hays, AAA Affair, Muhammad bin Carrying al Razz, Bin al-Naifs were inevitable in the scientific history. All bin Shall Arabian al-Tabor was an Islamic scholar, physician and psychologist of Zoroastrian descent, who produced one of the first encyclopedias of medicine. Even the number system we used today was introduced systems Let's have brief a look on the other civilizations which contributed to the science.Like the crest on the peacocks h ead, like the gem in the cobra's hood, so stands mathematics Oat the head of all the sciences. Vided literature of Indian Culture is replete with concepts of zero, the techniques of algebra and algorithm, square root and cube root. Arguably, the origins of Calculus lie in India 300 years before Leibniz and Newton. Algebraic theories was developed by Rapacity who lived in 5th century C. E. ND another mathematician Backbencher's was the first to was the first to conceive of differential calculus in 12th century. Most of us are familiar with Roman numerals.Think you are sitting in a class doing Calculus using Roman numerals. You are going to write 1788 in Roman numerals it will be ANTICLIMACTIC. You even can't think of doing calculus by using this number system. From this we can conclude that calculus was not developed or used in early Europe. Ancient Indian's development in chemistry was also in a higher level and used in a variety of practical activities. In any early civilization, m etallurgy has remained an activity central to all civilizations from the Bronze Age and the Iron Age, to all other civilizations that followed Indian achieved the higher level of metallurgy.By the side of Stub Minor in New Delhi, there is an iron pillar erected during Array Guppy period around 500 AD. This pillar is 7. 32 meters tall, and has a circumference of 40 CM in the bottom and 30 CM at the top. It has been standing in the open for last 1500 years, withstanding the wind, heat and weather, but still has not rusted, except minor natural erosion. This kind of rust proof iron (steel) was discovered very few decades fore by mixing carbon with iron [4]. 3 In addition, the Chinese Dynasty in the Far East was producing gunpowder, paper and establishing printing presses.Moreover, the Calendar system was introduced by Amman civilization that is very famous for predicting apocalypse of the earth. From the above arguments, one can conclude that science was not only originated from Greece and it originated universally. Then how did the story â€Å"Science was originated in Greece† came into play? Moreover, where was it originated? These questions can be answered in two simple words â€Å"Church† and â€Å"Power†. From the time hen the state and the church merge, Church initiated the program of distorting history to promote its power.This technology of falsehood was now applied to â€Å"manage† common perceptions[5]. During the crusades, church captured many text and tent to use them. But theological aspects would not allow them to use a Muslim knowledge. Therefore, they manipulated their people by saying that the knowledge Arab had was belonged to Greeks. Arabs Just preserved it. This story enabled the universities in Europe to use translated Arabic books without contradicting their theology. But on the Arabs side, it was a different story.They built Batty al Hickman (House of Wisdom) in Baghdad; they gathered knowledge from all over the world, including India, Persia and China. They certainly did not restrict themselves to Greek Arabs only had sources to Greeks. So all the knowledge which was acquired from Batty al Hickman in Baghdad became the Greeks, So did all the scientific inventions and discoveries. This theory is being promoted by many scholars of the present too. Here is an example from Lost in the Cosmos by Walker Percy â€Å". .As Whitehead pointed out, it is no coincidence that science sprang, not from Ionian metaphysics, not from theBrahmins-Buddhist-Taoist East, not from the Exceptionally astrological South, but from the heart of the Christian West, that although Galileo fell out with the Church, he would hardly have taken so much trouble studying Jupiter and dropping objects from towers if the reality and value and order of things had not first been conferred by belief in the Incarnation. † [6]. So anyone from any country has the right to say that their ancestors were also one of the pioneers o f the science. It is time stand up against the â€Å"West only theory'. The Europeans not only colonized our countries but also our education system.They left our countries long ago. Now it is time to decolonize our education system. And the way we think. 4 References [1]Dunn. Ancient Egyptian Science retrieved from http://www. Torturers. Net/ featureless/sciences . HTML [2] Raja, C. K. Euclid and Jesus. Multiversity.

The Boy at the Window

The Boy at the Window is a poignant poem written by Richard Wilber. According to a statement made by Wilber, it was inspired by his five year old son being concerned about the possible danger his newly completed snowman was in due to a pending storm. Poetry is often recognized for its ability to evoke strong feelings in the reader and the beautifully innocent nature of Boy at the Window exemplifies this magnificently with skillful use of personification and beautiful use of metaphors. The story starts with painting a bleak and very serious over tone, seemingly from the overly dramatic perspective of a young boy as told by an omniscient outside perspective. The dire aspect of the snowman’s situation being a wholly terrifying experience to him, as seen in lines three and four of the first stanza, â€Å"The small boy weeps to hear the wind prepare/ A night of gnashings and enormous moan. † It is apparent that, to this boy, this is a huge menacing storm blowing in and threatening his snowman. It is further defined in the use of personification to describe the prediction of the storms violence, gnashing and moaning, both human qualities with tendencies of use in both pain and anger. Gnashing specifically paints an intense image of something being grinded between two forces until destroyed is extremely impacting. The line following in the poem is a description of the snowman’s facial aspects as seen by this young man, showing a desperation and betrayal as compared to the biblical story of a God- forsaken Adam looking into Eden for the last time. It adds a touching depth to the fear that this young man is in grips of and it is representative of the emotional transfer to the snowman in a young boys mind. The second stanza is written from the snowman’s perspective, which as a statement in its self shows personification. I find that the fact that the snowman experiences feelings in a very heartfelt way, showing a warmth of humanity and empathy. These traits come into a clear light in the 13 and 14th lines of the poem: He melts enough to drop from one soft eye/a trickle of the purest rain, a tear. This shows the depth of humanity portrayed in the snow man and the tasteful use of it within the story. The writing in the poem is elegant and beautiful, using a rhyme scheme and the occasional assonance to keep the flow while not maintaining a strict adherence to a set pattern, throughout the poem there are moments of striking imagery and powerful emotionally gripping perspectives which adds to the innocence of the child’s perspective and the humanity shown in the snowman; it is, in short, great writing. Great poetry is able to evoke strong feelings in the reader, making them think beyond the words on a page and take the images painted with the writers craft into their imagination and heart. The book says, â€Å"it is more accurate to say that poetry is an evocative response to ordinary life experience (Clungston, 2010)†. I think watching empathy grow in a child’s eyes and the personification of a snowman combine to paints a beautiful picture of the innocence of youth and the amazing experiences of watching someone slowly mature and grow before your very eyes.

Presentation of a Research Article - Essay Example that nurses and doctors believed that their main purpose was to raise the issue of obesity, but that the responsibility for treating it is with the parents. Another major point in the article was that the doctors and nurses believed that because of time constraints, a lack of training, and ill-defined roles they were not able to aid children with obesity issues. Still a third major point was that the child and medical professional relationship could be compromised or jeopardized if the issue of obesity was raised, as they recognized the issue of obesity was a sensitive issue. The major point was that these individuals believed they were ill-equipped to deal with the issue as they believed simplifying informing the patient to engage in more diet and exercise would be ineffective. These cumulative perspectives formed the backbone of recognition and understanding within the study findings. There are a number of further concerns. In terms of generalizability the study is a qualitative study and as such is generally considered as only being applicable to the set population group (Creswell 2003, p. 40). Still, Creswell (2003, p. 42) indicates that qualitative study designs may hold the same level of generalizability as external studies. This consideration indicates that this study could potentially be considered as indicate of broader ranging doctor and nurse perspectives on the nature of obesity treatment. In terms of validity, it seems apparent that the study followed the accepted guidelines for qualitative research. However, there is no way to determine if the study precisely recorded the interview respondents answers or conducted the interviews in a valid and unbiased way. Ultimately, it seems that the study holds a great degree of worthiness. In these regards, the study identified a significant and pressing gap in research. Namely, medical professionals perspectives on treating obesity. As there are a variety of shortcomings in this treatment approach, the value

Critical review on the ratification of principal to the third party Essay

Critical review on the ratification of principal to the third party - Essay Example Here we may cite another example of agency contract in respect of employment of suitable candidates. Numbers of companies are hiring the services of HR consultant to assist them in right sizing and locating the valuable human capital to meet the desired objectives of their companies through rigorous selection process. Moreover, in the shipment of goods to their destined port, the role of clearing and forwarding agencies are worth praising in terms of their services. It is not necessary that the whole tasks of the company be assigned to the agency that performs certain jobs on behalf of their clients. Many relationships do not necessarily require involvement of agency services. Hence, contractors and providers of goods and services do not fall within the category of agency relationship. There are number of laws, which an agency has to follow to perform certain tasks at the behest of their customers. In this particular situation, the law of contract plays key role in defining and discharging responsibilities within the framework. In fact it’s a tripartite relationship amongst a) Self b) Principal and the c) third party. In other words it is a special kind of contract under the agency contract. The principal contract which executes between the principal and the third party is implementable on either sides in favour or against and has the same repercussions as the principal has for self. Since there are no privets of contract between the agency and the third party who had signed the agreement, therefore, the agent has the right to step down. Let us see the important ingredients, which are required to establish an agency a) by signing an agreement b) functional in accordance with law c) authority to strike a deal and d) ratification the act of agent who in some areas does not enjoy the authority of principal to do so. The agency has to perform number of tasks strictly in line with the agreement made

Growth Management vs. Growth Control Research Paper - 1

Growth Management vs. Growth Control - Research Paper Example The community has for years faced poor infrastructure especially in the suburban areas. In its effort to overcome this problem, the mayor invited Dr. Freilich of the London School of Economics to advise him on Growth management policies. This enabled the transport network of the suburban areas to improve. The growth management policy has eased traffic in San Diego. The current and future generations of this community will benefit, and this will foster growth in other sectors (Levy, 2011). In addition, the community uses a tiered system of separating the rural and urban areas. This is as opposed to the old growth boundary line that was in place before implementation of growth management policy. The tiers help the authorities to identify the areas that need more resources in development (Levy, 2011). This ensures that there is balanced growth in the region. Apart from transport sector, growth management has focused on other areas in San Diego. These include housing, sanitation, industrial and commercial sectors. This has made San Diego a conducive environment for its residents and generations to

Administrative corruption Research Paper Example | Topics and Well Written Essays - 750 words

Administrative corruption - Research Paper Example Lastly, the paper will explore the consequences of corruption and ways to deal with these consequences. Nevertheless, this essay focuses on presenting a discussion regarding administrative corruption in terms of types, cause, effects, and consequences. Definition According to Myint (3) corruption in its basic form regards to a form of dishonesty or fraudulent behaviors, by people in power, which may involve bribery, bribery, nepotism, extortion, embezzlement, and favoritism or involvement in actions that make people to be morally depraved. Types One of the forms of corruption is bribery that receives a substantial share of references, whereby people a bribe as money or favors for influencing a public official and it is in form of fixed sum, percentage of contracts favor in money in kind that is given to a state official. It also related to the bribe given to a state official to make a contract on behave of the state or business with a distribution of the benefits to the companies or the clients. The other type of corruption is nepotism that occurs when the administrative offices favor their relatives or close friends for a position in organization; especially if they hold a high position that involves decision making. This form of corruption is natural to human beings, whereby they can give preferential treatment to their family members and friends. For example when a student is a relative to the principal and the teachers are reporting low marks in subjects he is taking, the principal can change the low marks to high marks, thus falling a victim of the temptations of nepotism. The other example of corruption involves police receiving of bribe from corrupt individuals to earn a favors by breaking the law, fencing stolen goods and others like extortions by police officers. Police may also engage in violation of individuals rights either by use of excessive physical force which is brutality, discriminatory arrest, or verbal harassment. Causes The first cause of c orruption is increases in the level of poverty in the society, whereby only the rich are favored, while the poor continues to sail in their boat of thrifty (Myint, 5). Apparently, this hinders them from enjoying their rights as citizens of a given country. Therefore, it becomes extremely complicated when it comes to dealing with the corruption in the in various administrative departments. For instance, police may receive bribes from public transport vehicles where by ignoring the vehicles (Myint, 6). They do not arrest those drivers that are over speeding, this being one of the main causes of accidents. The other cause of corruption has also been evident through effects of political influence on administrative officers with differentiated political affiliations (Myint, 8). Certain politicians manipulate the some administrative officers in order to achieve their inclinations by using bribes, threats and nepotism; thus, politicians and leaders have increased ability to perpetrate corr uption in the society, and this has negative impact on members of the society. Effects Corruption in organizations has economic effects on the community relating to categorization of being major or minor, though both of them have a serious impact on the individual community. Corruption results to depletion of resources or the national wealth, thus taking the responsibility for the increase in the cost of commodities, funneling of scarce public resources, leading to uneconomic projects at the expense of the need projects by the public such as schools, hospitals and improvement of infrastructure in the society, and it also contributes to misallocation of resource, conversion of

Globalisation Of Marketing Design and Innovation Dissertation

Globalisation Of Marketing Design and Innovation - Dissertation Example According to Doyle, innovation, as a marketing strategy, has several times proved to be the key factor to reward success to many businesses. It is also considered to be the path of attaining higher growth in terms of sales, market shares, and others. However, innovation can be referred to as the development of a newly designed product, marketing channels, and marketing concepts. Thus, innovation in marketing can be stated as one of the crucial elements to achieve an efficient competitive advantage and growth. This statement can be well-observed in the case of television industry where analysts claim to witness an extraordinary chain of innovations which brought about changes in shape, color, size and other features of the genre. For instance, Lachenbruch stated that in its performance from 1953 to 1956 the television industry reached its maturity similar to radio and phonograph industries. It was the period when almost every household in America had a television set in their living r oom and thus sales of television begun to fall. By that period, a new version of television was introduced to the market, i.e. color TVs. This innovation again took the industry to its growth.   These kinds of evidence can be witnessed in almost every stage of the industry, especially in terms of style and technology. This shall be evidently identified in the further discussion.  The introduction of television can be identified in the early 1920s when television was presented in two broad paths.

Legal Aspects of Contract Adminitration (LAW) Coursework

Legal Aspects of Contract Adminitration (LAW) - Coursework Example The contract becomes valid only if it fulfilled all the legal requirements. Contract is the agreement enforceable by law so that agreement may be either for tender or for acceptance. The offer become valid only if it meets the entire requirement specified in the contract law in Australia. Those are as follows, There are normally six important ingredients essential for lawfully connecting the contract development. That are (1) agreement it consists of offer and acceptances made by the parties to the contract, (2) Offer must be made for the Consideration either in terms of money, property etc., (3) ability to enter lawful relationship between the parties to the contract it means the party to the contract must possess sound mind as well as majority of age, (4) Intention by the groups to enter into lawful affiliations, (5) must fulfill the requirement of the valid contract and (6) certainty. Contract may sometimes also turn into illegal contract if it fails to fulfill the requirements. The Australian lawful scheme is based on a basic faith in the rule of  law, fairness and the autonomy of the judiciary. An offer may be broken by revocation, rejection or drop. An acceptance is, usually conversation; a whole and ineffectual assent to the complete the circumstances that include an offer. Inten tions must be understandable and extremely a great deal evident previous to creation whichever contract. In this particular case Mr. A who thinks that he had concluded an agreement through Mr. B to buy a one third interest in D pvt. Limited from Mr. But at the same time Mr. B sold the same to Mr. C. On the other hand Mr. A notifies that he thinks an agreement among Mr. A and Mr. B to but the interest had previously been arrived at as the effect of two or three emails exchanged through Mr. B. In The first mail itself Mr. A sent Mr B a draft contract prepared through the lawyer on with no prejudice base. Second mail was sent by the Mr. B to Mr. A. In this

Doing Business in China Essay Example | Topics and Well Written Essays - 1500 words

Doing Business in China - Essay Example It is a challenge that every businessman should take if they want to succeed. This paper provides information on how to do business in China. Relying on current literature for ideas and examples, it gives recommendations on how to deal with the Chinese and establish business in China. According to Hamilton and Jhang (2012; p.4), â€Å"China is one of the most dynamic markets in the world in which change is the only constant.† By saying this, Hamilton and Jhan point out two things about China. The first one is dynamism, and the second is change. These two things suggest the main challenge in doing business in China. Dynamism is evident in the country’s culture, political makeup and religious beliefs while change is constant and rapid in its economy. Therefore, knowing aspects of dynamism and change will give businessmen an edge in their Chinese ventures. Culture Dynamism can be found in every aspect of the culture. Importantly, every foreign capitalist should be aware of the Chinese culture in order to act according to it. Otherwise one will lose all the chance to even start business in China. Culture is a very important aspect in doing business. There are practices that should be observed and non-observance would mean ignorance and lead to failure. The most important value that the Chinese has when doing business is guanxi. This term means goodwill. ... West (2007) claims that in doing business with the Chinese, especially with the northerners, one must exercise, â€Å"eat first, talk later.† This is the same throughout China but the southerners have become more Westernized in doing business, especially Shanghai people. Nevertheless, the culture of guanxi is respected throughout the Mainland. Establishing guanxi is like developing brotherhood in the West. Along with it is showing genuine sincerity with Chinese partners. According to Hamilton and Jhang (2012), genuine sincerity goes a long way in China but not all businessmen realize its importance. Non-Chinese people think of Chinese as corrupt, possibly because of the practice of guanxi but they should understand that guanxi is not similar to bribery. Many Chinese do not accept bribes for jobs they ought to do. For instance, one taxpayer gave a significant amount of money to a banker in gratitude for the fast transactions they had with the bank. When the banker saw it, he di d not feel the need for the gift and credited the amount to the company’s account. This act illustrates that bribery is not the way to do business in China. Similarly, foreign visitors are not obliged to give tips to the Chinese. Tips in hotels and restaurants are welcome but they are not expected. The Chinese people appreciate tips even in small amounts but they will do their job even without tips. Greeting them, exchanging stories and smiles are more valued, as it goes with business. One thing that is valued much in China is presence. According to Hamilton and Jhang (2012), visiting often will create goodwill among the Chinese. They cite that Hank Paulson, former CEO of Goldman Sachs, spent 70 visits in China, thus making him well-regarded in the country. Another man named Jim Rogers, an

An Unpredicted New kind Of Warfare Essay Example for Free

An Unpredicted New kind Of Warfare Essay World war one continued for four years across a vast and stretching from the English Channel to the northern Swiss border. In 1914 the prediction was that the war would be over by Christmas. At the beginning of the war, The Germans thought they could capture France before invading Russia therefore preventing a war on two fronts. But because of the failure of tactics they couldnt succeed, and this was one of the main reasons the war lasted for such a long period. It was no longer each side trying to capture the other in the war but stopping the enemies movements in trench warfare and using new technology to soften up enemy, if it didnt back fire. Defense was now the key to winning the war and was far superior than the offensive. The trenches were hard to capture by advancing troops because of increasing firepower from machine guns. Crossing no-mans land was committing suicide for the troops as machine guns could inflict enormous damage on advancing infantry. The realization of the advantage of defense resulted in the enhanced rate of advancing technology. This was one of the core reasons for stalemate upon the Western Front because technology was advancing at such a rapid rate and new inventions were being introduced in a hasty manner. Many of the new inventions were not sufficiently tested and many of the ideas were not thoroughly thought through which resulted in unnecessary delays. Aircraft at the start of the war was used primarily for reconnaissance work, spotting enemy trenches and movements before a possible attack. But this alerted the enemys attention and gave them time to prepare resulting in the attackers job being more costly and difficult to undertake. Barbed wire was massed produced on an industrial scale by both sides as barbed wire entanglements were unbreakable for troops, stopped cavalry in their tracks, and slowed troops down completely. Attempts were made to destroy barbed wire with shellfire but the barbed wire is just lifted and often ends up in a bigger mess than before. Chlorine gas was first introduced in April 1915 by the German army against the French army. Chlorine gas destroyed your respiratory organs and you had a long slow death. But poisonous gas was an extremely unreliable method of attack as the direction of the wind may change at any time and return the poison in the direction of the attacker killing your own troops. Also, as with many other weapons that were developed it can only be used once to an advantage, as their element of surprise is lost. Gas masks were quickly distributed to both sides and gas was not such a great fear as it was first thought Tanks were invented to be the technical solution to the major problem of both barbed wire and machine guns. They had an armour plate to protect troops whilst attacking and caterpillar traction to allow them to cross-hilly and muddy ground. But the first Mark I tank was a weak and variable weapon. It was used at the Somme in 1916 but neither their performance nor numbers could help win the battle. It was not until Cambrai in 1917 that tanks were used on a large scale. They crunched their way over the barbed wire and German trenches creating a huge hole in the German defenses. A General on horseback commanded his armies in battle up until 1914. After 1914 telephones were working. Battles could be safely won from far away behind a desk. But though this development in communications may seem a great success, but telephones in reality were useless in attack, because the commanders didnt have a good perspective of the war and didnt know everything as they would be if they were sitting on horse and overlooking the battle which led to troops often pulling back because of lack of communications and broad view of the battle. In 1914 neither the French nor the British armies were trained for trench warfare. They had to adapt which took them several years and accounted for several of their failures and delays. French generals felt infantry charges were a necessity to win the war despite the huge advances in technology. And Germen generals thought that with enough ammunition and man power and gradually wearing down the enemy they would win the war. Eventually in 1917 the French army refused to attack any more, only to defend because of the horrific numbers of casualties lost for only a few miles gained. A term to explain this was the cannon fodder. The battle of Somme in 1916 is a good example for a shocking case of awful miscalculations by the leadership of both sides; Britain lost around 419,000 men for only a strip of land about 25 km long and 6km wide. These huge loses were due to bad planning. The men were untrained and advanced towards the enemy walking and carrying heavy packs on their backs. These big pushes which was a belief shared by British Kitchener and Haig were mere execution of sides troops as they were walking straight into machine gun fire. The first World War was the first war between two vastly industrialized economies and factories on both sides mass-produced inconceivable amounts of artillery and ammunition. Industry was under an incredible amount of strain and it was not until 1917 that the munitions industry was able to produce adequate quantities of ammunitions. Railways played a major part in the transportation of troops form one area of the western front to the next along with food and other supplies. Both sides were also both able to keep going because of the huge numbers of men and supplies continuously brought by trains and trucks. Basically both the central powers and allies were never in a drought of resources. At the outbreak of war on the Western Front, the Allies and the Germans were relatively equal in their strengths and weaknesses. Bad leadership held up many of the British and French attacks resulting in unnecessary numbers of casualties. Germany spread its men out over many of the fronts not only in the eastern front, but also in the Western Front. One argument is that if perhaps they had concentrated on only one front they may have had a chance of success as opposed to spreading out the troops over a large area. The deadlock ended in 1918 when it was broken by eventual collapse of the central powers. It was ultimately attrition that proved the crucial decider but it was a series of events and inventions that had not happened before which gave way to the end result. The submarine campaign was important as it brought America into the war with fresh troops and much needed resources and resulted in a huge blow to the German morale. In conclusion, there was no one true reason for deadlock on the western front, but that it was due to several problems. Technology advanced too rapidly, generals were not adequately trained for trench warfare. As one quote would say The great war was fought with 20th century weapons and 19th century tactics. The war was able to be kept going due to the fact they were both vastly industrialized economies and neither side was able to eliminate the other since and the governments of both sides directed the industries towards mass production of uniforms, ammunitions, ships, explosives etc

Cultural Differences in Shakespeares Work

Cultural Differences in Shakespeares Work Shakespeare in Performance This essay will explore the cultural difference of two Shakespeare, Othello performances. The two performances used are Stuart Burges 1965 adaptation and Oliver Parkers 1995 version. William Shakespeare was born in 1564 the son of John Shakespeare a glove maker, and Mary Arden the daughter of a farmer. Within the Elizabethan class system Shakespeare wouldnt have be destined for great things as he wasnt born into a significantly wealthy family. It is possible that Shakespeare was brought up as Catholic; Romeo and Juliet is a Catholic play. Shakespeare attended grammar school In Stratford his education would have been very intense in language, Latin, Greek and possibly modern language like French, his schooling would have also been heavily religious. Shakespeare would have been expected to leave school and go into law grammar schools trained for professionals. Shakespeare didnt continue his education at university and age 18 married Anne Hathaway and lived a quiet life having his first child, Susanna in 1583 then twins Judith and Hamnet in 1585. Historical accounts of Shakespeare in the first seven years of his childrens lives are classed as lost years, due to ther e being no reliable accounts in this period. It wasnt until the late 1590s that Shakespeare was writing plays although in them times writers would write under a false name so critics couldnt dismiss their work. By around 1591, 1592 Shakespeare had written 57 plays in the space 20 years this is a colossal amount especially as a play writer in the Elizabethan period. Shakespeare died on the 23rd April 1616 the same day as his birthday. The importance of Setting The plot Othello is taken from an Italian story Un Captitano Moro some critics believe, written in 1565 by Giovanni Battista Giraldi Cinzio, the story about a Moorish general deceived into believing his wife is being unfaithful. Shakespeare added important characters to the story Iago, Roderigo, Desdemonas father and Brabantio, Shakespeare implies the action of the play runs over some course of time although it could be perceived as being set over a period of a few days. Shakespeare also developed the complex villain Iago compared to the minor one in the original. Shakespeares audience would have believed in The Great Chain of Being, that determined the natural order of events. God being the top of the hierarchical chain, Shakespeare used the Great Chain of Being as a concept to emphasise the tragedy in Othello and struggle with love and Desdemona and Iagos jealous passion. Othello, the Moor of Venice scholars believe was written in the period of 1601-1604, Queen Elizabeth had died in 1603, people worried what would become of governess since Elizabeths death a lot of the fear is portrayed through Shakespeares plays of successful succession and governance. The Protestant Church of England was created by Henry, Elizabeths father there was concerns that the religion might fail after Elizabeths death in a Catholic came to power, and a foreigner to rule. Although the title implies Othello occurred in Venice it took place in Cyprus, having said that Shakespeares stage directions are very basic and minimal so directors that remake Shakespeares pieces can decide where the plot is set. In the period when Shakespeare wrote Othello Venice was a Republic that thrived on multiculturalism, it was major for international trade, Venice had colonial power also respectful of different cultures and religions. Venice was a charming, safe, peaceful location. Cyprus when Shakespeare was in school was under power by the Ottoman Turks, Cyprus was the home of wine and prostitutes full of deception and death. Geographically located between the Middle East, Europe, Mediterranean and Northern Africa the religion is Christian and Muslim, a prime place for religious and racial violence. Although critics believe Othello was adapted by Hecatommithi, the time period that Shakespeare wrote Othello Venice would have been a highly important trading link between the East and Europe. Venice would have been sending ambassadors from Venice and the East to Elizabethan England Shakespeare may have studied theses exotic strangers. Venice and Turkey during the fifteenth and sixteenth centuries would have been at wars thus Othello being the general of the Venetian war. Shakespeare cleverly adapted a plot surrounding the issues of the day and explored a twist on race, jealousy and deceit. During the Elizabethan period, black people were not regarded as slaves, in 1601 Queen Elizabeth granted the diplomatic rights which allowed deportation, due to fears of overpopulation. Although the salve trade was not established during this time, the black race was considered inferior. Othello is a revolutionary cultural work, as the Moor Othello is portrayed as a civilized noble Christian who was wrongly deceived forced audiences to rethink the racial status during the early 16th century. Moor was a term used by the Elizabethans referring to Muslim Arabs or North Africa who had conquered Spain in the eighth century. Moors were Elizabethans believed, sinful, animalistic and murderous. It is interesting that Shakespeare represents Othello as the wrongly deceived victim, and Iago the Caucasian the typical More stereotype. Othello The tragedy of Othello, the Moor Whom Is general of Venice, promotes his lieutenant Cassio, leaving Iago enraged with jealousy. Othello fell in love and married Desdemona daughter of Brabantio, the Venetian senator. Iago uses Desdemona and Othellos love as a tactic in his revenge. Iago manipulates Othello into thinking his wife is having an affair with Cassio, Othello outraged kills Desdemona before killing himself the story concludes with Iagos unmasking and execution. Stuart Burges 1965 Othello Laurence Olivier The first English language film of the play Othello was released in December 1965 by director Burge, Burge was born in Brentwood Essex in January 1918 and died in 2002. Burge was the director of the Nottingham Playhouse between 1968-74 then went onto be artistic director at the Royal Court Theatre in over the period of 1977-80. This is the only Shakespeare adaptation that all leading actors were nominated for Oscars. The film was nearly exactly the same as stage production the release did not make use of music of exit music. Burges version of was the first English Othello shot in colour it had previously been done in Russian. This was the first of Shakespeares original text created into a full length British feature. Lawrence Olivier played Othello and acted in blackface, critics over the years have argued the origins of Othello being black or Arab. Othello has been played by white and more recently black actors, Laurence Oliviers version was performed in blackface. Olivier went into detail of his black face performance in his autobiography; Black all over my body, Max Factor 2880, then a lighter brown, then Negro number 2, a stronger brown. Brown on black to give a rich mahogany. Then the great trick: that glorious half yard of chiffon with which I polished myself all over until I shone the lips blueberry, the tight curled wig, the white of the eyes, whiter than ever, and the black, black sheen that covered my flesh and bones, glistening in the dressing room lights. (L. Olivier 1965) In Oliviers autobiography; Olivier, Laurence. Confessions of an Actor, Olivier proclaims in his and the directors minds the blackface wasnt done in a minstrelsy way it was done as costume to make him up as African with innocent intentions of playing Othello. The text Othello is not completely clear on Othellos race, subsequently because Shakespeare would not have been completed educated about the people that lived in North Africa. In 1966 the civil rights movement was at its highest in America racist discrimination and stereotypes were challenged the aesthetic of the Oliviers blackface was out of date and political incorrect.   Although in Europe, the civil rights movement wasnt as big as America with the last white actor blackface Othello taking place in 1990 by Michael Gambon. The New York Times published an article about Oliviers performance that stated; Outrageous impression of a theatrical Negro stereotype, Olivier an end man in an American minstrel show. (the New York times, Bosley Crowther) Burges adaptation of Othello definitely brings the issue of race to the forefront, most of the racial language is present as in the 1604 original text; thicklips, being the first derogatory offensive language aimed at Othello Act one, Scene one. Venice. A street. Roderigo: What a full fortune does the thicklips owe if he can carryt thus! References made by Othello regarding his race are interpreted as intended by Shakespeare, delivered with doubt; Act three, Scene three. The garden of the castle Othello: Haply, for I am black. Intending that because he is black, he is not as sophisticated as other people. Burge directed Olivier as a stereotypical African, exaggerated gesture and accent with his costumes ethnic and predominantly barefoot, with a rosary necklace. Burges performance has been regarded by critics as the greatest performance of the 20th century. (Peter Rainer) and was nominated for four Oscars, winning one. Olivier is the first of the great twentieth-century British actors who has created a brilliantly original interpretation of Othelloà ¢Ã¢â€š ¬Ã‚ ¦ (Oliviers) Othello is a man of gigantic stature but he is not a man of titanic thought; and by no means is he umo univerale, a man of many sided character, typical of the Renaissance. This Othello came into the world from a less civilised society. He Is very close to nature, to the earth. He has had no time to absorb the culture of the new world surrounding him. With all its glitter, this world is in fact trivial and meanà ¢Ã¢â€š ¬Ã‚ ¦ Othellos simple soul makes him vulnerable to the pretty contrivances of the environment. A civilization that is false and untrue kills the simple-minded manà ¢Ã¢â€š ¬Ã‚ ¦ this is what Olivier; the actor shows us. (in Tynan, Othello. National Theatre Production, 108). Every modern, white actor, takin on Othello, feels obliged to explain why hes not playing him black, which was surely Shakespeares intention, when the unspoken reason is that to black up is as disgusting these days as a nigger minstrel show. (Laurence Olivier, 1986) Each generation can use pieces of Shakespeares texts his writings are timeless, an Author who makes plays relatable to different generations thus why Othello has been adapted countless times since 1601, in some adaptations of Othello the play is portrayed mostly on the jealous and devious theme. Burges approach to play directions however have been deemed as a play about race. A film version of the 1965 production released on DVD by Warner Home Video in 2007. Oliviers blackface performance makes this film adaptation a difficult object of study, but since it makes Othello a play about race in a way so disturbing for postmodern sensibilities, it is a valuable tool for exploring racial difference as a theme. And especially for considering the plays particular resonance with contemporary racial politics. (R, C. Evans In an article by the New York Times published February, 1966 reporter Bosley Crowther describes how America portrayed Oliviers performance; Seeing as how the drama critics in England were unstinting in their praise of the lush stage production of Othello in which Sir Laurence Olivier played with the National Theatre of Great Britain a couple of years ago, it may seem rude of an American film critic to voice some startled expectations to the motion picture made of the play by a British company. One bold and singular aspect of this production immediately impels the sensitive American viewer into a baffled and discomfited attitude. This is the radical make up Sir Laurence has chosen to use in his powerful and passionate characterization of the jealous Moor. He plays Othello in blackface! Thats right, blackface not the dark-brown stain that even the most daring white actors do not nowadays wish to go beyond.   Whats more, he caps his shiny blackface with a wig of kinky black hair and he has the insides of his lips smeared and thickened with a startling raspberry red. Several times, in his rages or reflections, he roll s his eyes up into his head so that the whites gleam like small mil agates out of the inky face. (B. Crowther 1966) Burges adaptation of Othello is clearly one that caused a stir, with the controversial blackface. The period in which Burge adapted the version the culture was changing surrounding racism, racist terms and what is politically correct. Professor Tony Howard University of Warwick believes for Olivier race wasnt an issue, race was an interesting factor in the play and he chose to make it paramount. The result of that was that I know some black actors that saw the play and were appalled by his imitation of stereotypical behaviour, and I know other black actors who saw the play and were inspired to become Shakespearian actors because of the sheer admiration for what he did. (T. Howard 2013). Oliver Parkers 1995 Othello, Laurence Fishburne Oliver Parker an English film director born 6th September 1960, directed Othello played by a black actor Laurence Fishburne classed as not an outsider in this version as the actor is of African descent. Having said that the racial tensions and most of the racial language still applies in the film. Fishburne, plays a more confidant, cocky Othello in this version he also wears the same costumes as most of the cast, with earings in his ears he blends in well with the rest of the cast unlike in Oliviers version. The choice of music and camera shots sets the racial tension in a different way than previous adaptations with the use of drums during the consummation of Othello and Desdemona also during the Cyprus   celebration. The film doesnt generally focus on Othellos race but more so on the tragedy of the story and Iagos jealousy. Parkers adaptation is more satisfying as a film rather than Shakespearian text, the original text is very heavily cut with many original rhythms not included. The plot and characters remains the same as the original text and Burges, parker sets the film within the same time period and location as the two explored. Parkers version is however modernised and update some areas of the film, parker has changed the interpretation of Iagos character slightly also cutting much of the original text. Parkers use of Othellos dreams allow the audience access into Othellos agony over his suspected wifes adultery, this opened the door to the audience in a new light, something that the original monologue and Burge was unable to achieve. The issue of Race in Parkers version is watered down and limelights the character of Iago and his evil plan. Iagos direct camera soliloquies, via direct camera shots portrays his devious intentions, Iagos true nature is heightened in Parkers adaptation through this technique compare to Burge and the original text. In Act one, Scene three Iago shouts to Roderigo to put money and love into his purse Iago is trying to deceive Roderigo into giving him money so Iago will make Desdemona fall in love with Roderigo. When Iago leaves this scene, the camera zooms in on Iagos face to music building up that creates tension, Iago then recites this original quote from the text; Act one, scene three Iago: Thus, do I ever make my fool my purse: For I mine own gaind knowledge should profane, If I would time expend with such a snipe. But for my sport and profit. I hate the Moor: And it is thought abroad, that twixt my sheets He has done my office: I know not ift be true; But, I for more suspicious in that kind, Will do as if for surety. He holds me well; The better shall my purpose work on him. Cassios a proper man: let me see now: To get his place and to plume up my will In double knavery-how, how? Lets see: After some time, to abuse Othellos ear That he is too familiar with his wife. He hath a person and a smooth dispose To be suspected, framed to make women false. The moor is of a free and open nature, That thinks men honest that but seem to be so, And will as tenderly be led by the nose As asses are. I havet. it is endgenderd. hell, and night Must brin this monstrous birth to the worlds light. During the speech by Roderigo, Parkers gives the audience a subsequent plot for throughout the play as to why Iago wants to kill Othello. Parker directs Iago to look straight into the camera whilst declaring his hatred for Othello this breaks the forth wall including the audience on the whole experience. Iago speaks in a hushed monotone to music playing in the background thus adding theatrical drama, the camera then pans down to a chessboard. Iago places a white queen, black king and a white knight on the board parker does this to replicate Desdemona, Othello and Cassio. The colour of the chess pieces also play a very clever crucial part in the film highlighting the racial but also the use of a chess board highlights the manipulation and game playing from Iago. Parker directs Fishburne to play overtly sexual compared with the Burge version and original text. Parkers directions continues shows Desdemona and Othello in bed together in a number of scenes to modernize the version to appeal to a different audience. Parker has Othellos dreams filled with adultery presented with Desdemona in bed naked with Cassio, in the Burge version the characters are a lot more innocent. Othellos visual image of Desdemona and Cassio, allows for his fear to come alive with the help of Iagos manipulation Othello remembers what Desdemonas father said to him; Act one, Scene 3 A Council-Chamber. Brabantio: Look to her, Moor, if thou hast eyes to see: She has deceived her father, and may thee. This line is continuously played in Othellos head throughout the film, giving Othello confirmation that the affair to real as Desdemona is deceiving him just as she did her father. Once you get to Act three, Scene three, its like being caught up in a huge surf. You are pounded by experiences and overwhelming feelings that oscillate violently. Sometimes within one sentence I go from passion and adoration to the most extreme expressions of loathing and self-hatred Ive ever had to try to get close to. (Laurence Fishburne, 1996) There are a few predominant themes that flow through both versions of Othello and the original text; Love, passion, jealousy, betrayal along with reputation and honour. love being the force that overcome a large obstacle in the marriage of Othello and Desdemona, although Othello loves Desdemona he gives her his heart he doesnt give her his mind and he doesnt trust her, he is deep down insecure.   Their love was tragically lost by the passion of Iago and his jealousy love to Iago is leverage, he declared his love to his friends but does the ultimate betrayal. The love between Cassio and Desdemona that is misinterpreted. Passion comes from Othello and Desdemona two lovers that political looked down on for the marriage but still going ahead with their passion anyway. Jealousy is a trait that is both in Othello and strongly Iago. Multiculturalism, Religious Suspicion and Racism. The Venetian Republic was known as a culturally tolerant society, that welcomes cultural traditions, however Othello and the merchant of Venice being set in Venice, portrays jealousy, race and xenophobia. Shakespeares Othello predates the slave trade and biological classification. Othello being a Moor in Shakespeares time could relate to someone from the Middle East or Spain not necessarily Africa.

Porters Five Forces Analysed The External Environment Industry Marketing Essay

Porters Five Forces Analysed The External Environment Industry Marketing Essay Among the different choices, Apple has chosen the differentiation focus strategy in the broad industry. The invention and development of products by Apple are its highly unique attributes, with devices such as the iPhone, iPod and iPad where the use touch screen and other interfaces to operate the products. Apple spends billions of dollars every year on RD (Research and Development) to develop and promote its products in order to achieve superior quality over competitors products. Apple slogan is Think Different, which drives them to innovate and provide high quality regarding their products. Apples markets are global, but they are focusing on active markets such as America, the EU and some Asian countries. However, Apple focuses on a market segment where customers clearly feel that Apple provides value for its customers. In addition, Apple had a positive growth rate during the economic crisis of 2007-2009 (Business week, 2010). Apples premium price strategy and its success have beco me a significant barrier to competitors such as Nokia, Motorola, HTC and the E-book by Sony. Porters Five Forces Analysis Porters Five Forces analysed the external environment of the industry in order to give a better understanding of the strengths and weaknesses within the organisation. These analyses give the company the ability to identify the opportunities and threats from external factors (Harrison, 2003). These forces include: Threat of new entrants For each of its product lines, Apple, like any other company, faces rigorous competition. This high-tech industry requires continual research and development (RD). This sector is difficult for new companies to enter because new entrants must spend a large amount of capital on RD and on the advertising and promotion of their brand. There are some dominant producers in this sector such as Apple, Microsoft, Dell and Sony, who share the majority of the market. Apple should be aware of new entrants because they may come up with surprisingly better technology or a better product. However, these new entrants are less of a threat because it is difficult to enter and penetrate the market in a limited time (Harrison, 2003). Power of the supplier Porters second force states that the bargaining power of suppliers imposes a threat to any company. It also includes, the availability of substitute suppliers which is an important factor in determining the power of the supplier. Suppliers are known as third parties in this industry, and they are classified in two groups. The first group makes the major parts for the products. This group is not strong because of the availability and easy of replacing the items they make, such as batteries, wire connections, screens and other internal components. In contrast, the second group provides accurate parts and important programmes such as flash-memory and DRAM. This group is strong because of their specialized and advanced products, as well as the lack of alternative products (Nistor, 2010). There are some suppliers who dominate the market; for example, Intel, Microsoft and Sony. So, it is important for Apple to have a good relationship with its suppliers. Power of the buyer The buyers bargaining power is very high in the industry because competitors offer a wide range of similar products with competitive prices. The Apple Corporation faces a moderate threat from buyers because they have a lot of products that consumers can choose from. In addition, the threat of buyers comes from their demand for new features in Apple products. However, there are a large number of companies that offer similar products and there is quite a big differentiation in price and performance. Therefore, loyalty is often shown towards a specific brand because there are not many differences in the quality and price between brands (Nistor, 2010). Buyers are often more sensitive to brand rather than price. Apples customers are individuals, education departments, enterprises, governments and creative customers. So, the variety of consumers and their needs has a direct impact on Apples future strategies. Threat of substitutes The technological environment is changing fast every day. There are not many substitutes in this industry because of the high-tech features. However, alternatives are always available from competitors. If some other company such as BlackBerry, Google, Samsung or Microsoft come up with new technology or the same kind of phone at a lower price or with more features at the same price, then this is a problem for Apple (O Grady, 2009). Customers usually tend to look to the latest technology instead of traditional methods. Apple has the ability and efficiently to design and develop its own hardware and application software to become unique and distinct from its competitors. Competitive rivalry The competition in this industry is very high, almost in all areas of business, because of the continuing requirement to provide new products all the time. Competitive prices, new products, design innovations and technology are the main factors that Apple has to compete with other international companies on, such as IBM, HP, Acer and Dell. The consumers choices also differ; some prefer to save some cash rather purchase high performance specification technology and some prefer the newest technology. So, the result is that companies implement different strategies; for example, low-cost and best-cost strategies. Some manufacturers offer products at the lowest price in an attempt to cut their costs by ignoring everything except some basic features. Some other companies in the middle price range, such as Dell and HP, focus on attracting customers by offering varying prices. And the top of the range companies, like Apple, gain customers through their high quality products, features and inn ovative design, which makes their products popular all over the world (O Grady, 2009).

Ramses :: Ancient Egypt Egyptian History

Ramses Ramses the Great ruled as the greatest pharaoh of all times. Also known as Ramses II, he was born in 1304 B.C., and was given the name the Justice of Ray is Powerful. He had the knowledge of the kingdom, and became the focus of the court at an early age. Ramses and his father spent most of their time together. As a young crown prince, Ramses II was appointed a co-ruler by his aging father, Seti I, and fully inherited the throne at age 24 when his father died. Even before he became Pharaoh, the young prince was known as a courageous warrior. At 22, he was sent to quell a minor revolt in Nubia. He brought along two little sons, and they took part in a chariot charge, according to a scene depicted in a carved relief on the walls of the Beit El-Wali Temple south of Aswan. After his ascent to the throne, the kingdom prospered and the young Pharaoh poured his energies and national treasures into building temples and monuments honoring his father, Egypt's gods and himself. In Nubia he constructed six temples, two of which were carved out of a Cliffside at Abu Simbel, with their four colossal statues of the king, are the most magnificent and the best known. Engineers designed the temple so every year on February 22 and October 22 the earliest sunrays shine on the back wall of the innermost chamber and lights up the pharaoh's statue, and fitting, he sits with the three gods of the sun. In all of his monuments he had his name cartouche and texts engraved so deep that no successor would be able to remove it. When Ramses became pharaoh, he had as many women as his heart desired and they were his greatest supporters. Ramses II built a king-size family with a 'considerable harem of wives and concubines'. He had 5 or 6 main wives and is known to have had more than 100 children with all of his wives. His favorite wife was the beautiful Nefertari, his chief queen and mother of his first-born son and other children. Ancient statues and inscriptions suggest she often appeared at her husband's side on state occasions and during religious ceremonies early in his reign. Ramses spent most of his 67-year reign reviving the empire and fighting the Hittites of Asia Minor. Ramses the Great, known for his fighting, went into battle with about 2,000 men in 1275 B.

Wolff’s View on Feminine Sexuality in Chopin’s The Awakening :: Chopin Awakening

Wolff’s View on Feminine Sexuality in Chopin’s The Awakening In her essay â€Å"Un-Utterable Longing: The Discourse of Feminine Sexuality in Kate Chopin’s The Awakening† Cynthia Griffin Wolff sees the lack of a language—for Edna Pontellier’s sexual desires in particular and female sexuality in general—as the main theme in Chopin’s novel. She particularly looks at how issues of sexuality remain unsaid in the novel, or how they are expressed in a different way, because of the lack of a language of feminine sexuality. As Ross C Murfin points out in his introduction to this essay, Wolff combines several theoretical perspectives such as feminism, gender studies, new historicism, psychoanalytic criticism, and deconstruction (376). Wolff introduces her thesis in her initial discussion of the opening passage of The Awakening stressing the fact that the parrot has no language of its own. She remarks that â€Å"there is a sense of enigma (or fraud) about this bird who seems able to communicate but is not† (376). Similarly the main character Edna Pontellier can’t communicate her needs. The first part of Wolff’s essay is a six-page assessment of the image of women current at the end of the nineteenth century showing the lack of a language for intimacy and sexuality. She looks specifically at the work of William Acton, an author widely read at the time. According to him women didn’t have sexual feelings of any kind; hence he saw no reason to talk about those issues. Wolff criticizes that this false image of women as a-sexual beings created by writers such as Acton also mislead the men of that time in their perception of women. Wolff argues that a â€Å"vernacular of ‘motherhood’† (386) replaced the missing language of intimacy and sexuality. In this context she refers to the passage when Là ©once comes home, Edna rejects his advances, and instead of reproaching her of neglecting her marital duties, he blames her for not taking care of the children. Là ©once turns the disappointment of the rejection into a reproach of neglected moth erly duties. According to Wolff, the true subject of Chopin’s novel, â€Å"may be less the particular dilemma of Mrs. Pontellier than the larger problems of female narrative that it reflects; and if Edna’s poignant fate is in part a reflection of her own habits, it is also, in equal part, a measure of society’s failure to allow its women a language of their own† (388).

European History - The Renaissance in Italy :: European Europe History

The Renaissance in Italy The Italian Renaissance was called the beginning of the modern age. The word Renaissance itself is derived from the Latin word rinascere, which means to be reborn. Many dramatic changes occurred during this time in the fields of philosophy, art, politics, and literature. New emphasis was placed on enjoying life and the world around you. Talented individuals sought self-gratification through art, literature, and architecture, and their achievments would influence future generations for centuries to come. This great new movement was originated and centered in Italy, and without Italian contribution, would never have launched European society into the dawning of a new era. At the beginning of the Renaissance, Italy was divided into some 250 self- governing city-states, ranging from small towns of 2,000 individuals, to some of the largest cities in Europe of that time, such as Florence, Milan, and Venice, each with 100,000 citizens each. These city-states were loosely organized under the Pope, ruling out of Rome, although he had no real political control over the divided Italy. During the mid- 1300s and early 1400s, many large Italian cities came under the control of one family, such as the Visconti and later the Sforza families in Milan. The form of government established by the ruling families of the various Italian cities came to be known as signoria, with the chief official being called the signore. Soon , elaborate court systems, controlled by the ruling families, began to spring up in each city-state. At these courts, leading artists, intellectuals, and politicians gathered under the sponsorship of the signore and families. Other city states had a form of republicanism, such as Florence and Venice did. In these cities, a group of upper class families controlled the government, and often looked down upon the common residents of the town, considering them to be inferior. A Venetian observer wrote about Florence during this time: "They are never content with their constitution, they are never quiet, and it seems that this city always desires change of constitution as so the government changes every fifteen years"(Cole p.218) In Florence, which is perhaps considered the most important center of Renaissance learning in history, the Medici family dominated the ruling class. Under Medici domination, Florence became a signorial power and a cultural gem stone. It was during the reign of Lorenzo de' Medici , that many great painters, sculptors, and architects flocked to the Medici family looking for sponsorship, knowing that Lorenzo was a great supporter of the arts.

Communication Technologies Essay

In this assignment I am going to describes different types of communication devices. For example Switches, Routers, etc. Then I am going to explain the principles of signal theory. After this I will look at difference methods of electronic communication and transmission used. Communication Devices Switches – These are mainly used for local area networks (LAN). The reason behind this is that they can be used to bridge a lot of computers together. They do look like hubs but they can vary in speed. They are more intelligent due to the fact that they can send out packets from a set port. There is advantage of using a network switch, they can be used with an Ethernet cable or a fibre optic cable and they still will work perfectly fine. When connecting a router or a server in an LAN or WAN network it is slightly easier because you would just need one cable which would mostly need to a fibre optic cable, so you can get the maximum rate of transfer speed. Routers – They are mainly used for connecting one network to another. They are meant for handling information and forwarding to another network connected to the router. You can either connect using wireless or a cable. Normally an Ethernet cable is used to connect the computer networks. Hubs – Also known as a concentrator or a multiport repeater. Used in a star or a hierarchical network setup to connect the station or the cable segments. There are two main types of hubs: passive & active. Active takes the incoming traffic, amplifies the signal and then forwards it all the ports. In a passive hub it simply divides the incoming traffic and forwards it. A hub can be used to manage and allow individual port configuration and traffic. Hubs operate on the physical layer of the OSI model and they are protocol transparent. This means that they do have the ability to set upper layer protocols such as IP, IPX or a MAC addresses. Hubs just extend them do not control the broadcast or collision domains. Bridges – Used to increase the performance of a network by dividing it into separate collision domains. Even though they are more intelligent than hubs due to the fact that they operate at the Data Link layer of the OSI model, they still are not able to control the upper layer protocols. On a separate segment they store the MAC addressing table of all nodes. Basically it takes the incoming frames and checks the destined MAC address and lookups it up against the store MAC addressing table and decides what to do. If the frame is comes from the same port as the destined port than it simply discards the frame. If the destined location is not known than it will be flooded throughout the outgoing ports and segments. Repeaters -One of the less complex hardware of the networking world, because it basically runs at the physical layer of an OSI model, so it is not aware of the frame formats and upper layer protocols. Repeater basically is used to expand a LAN network over large distance regenerating a signal. When using a repeater remember the 5-4-3 rule which means that a maximum distance between two hosts on the same network is 5. Use only maximum of 4 repeaters in a network and only 3 segments can be populated. Gateways – Very intelligent devices, they work at the Transport Layer protocol. This is higher than the Upper Layer protocol. This means that can manage and control IP, IPX and MAC addressing. They allow IPX/SPX clients to IP/TCP uplink network to connect to the internet. A gateway in simple terms is like a post office. All the information is sent to it and then as a post office knows the number of houses in the area in the same way a gateway would know all the ports and direct it there. Cell Phones – It is a piece of device which is used by a lot of people. It is a portable version and more advanced version of a normal home phone. It lets you voice calling, text messaging, the some other advanced phones even allow video calling and internet browsing. Cell phone is a full duplex device therefore you can connect it to your computer and use it as a modem even though it would be very slow. The newer released phones are somewhere near capable of the proper modem speeds. DCE & DTE devices – Data Communication Equipment (DCE) is basically equipment which allows communication with a Data Terminal Equipment (DTE). In another words DTE ends the communication line and a DCE provides the path of communication. An example of an DCE is an modem and a computer is a DTE. Fax Machine – A device which allows you to send paper copies using PSTN lines to other people. It can also be used to send memos and other information as well. It uses the phone line to transmit the data that is sent. A fax machine has a sensor to read the data and the end of it. It will encode the black and white that it picks on the paper and moves it to the receiving end. It will compress the data before transmitting it. As soon as it receives the data it decodes and decompresses the data so it can arrange it in the way that it scanned it from the original document. There are a lot of things in a fax machine that allow it to do its function. It consists of a source projecting a light beam, a rotating cylinder and a photo electric cell. It also has paper feed like a printer. E-Mail – Email also which is the short form for electronic mail. You can use e-mail to stay in contact with your friend/family even colleagues. It does it by finding out the person you want to email he’s email address and then you will send him an email and click send and then that person will receive it. Signal Theory When talking about signal theory data is represented by digital format which is dependent on binary or base 2 principles. Analogue and digital frequencies are used for transmitting signals along a medium link. Analogue records the waveform as they are. Digital on the other hand turns the analogue signals normally to sets of number. Analogue signals can have varying amplitude and frequency. Amplitude analyzes the loudness of the signal and Frequency determines the pitch of the signal. â€Å"Pitch† mostly used to refer to low and high notes. If the frequency is lowered than you get a low note and if the opposite is applied than you get a high note. Bit is a binary digit which represents value of 0 which is normally off and 1 which is normally on. Bit can also be referred to as a electrical pulse which is generated by the inner clock in the control unit or data register. Bit can also be used for digital electronics which is another system that uses digital signals. Manipulation o f a bit within the memory of a computer can be kept in a steady level on a storage device as a magnetic tape or disc. Byte which is made up of 8 bits is a unit measurement used for information stored on a computer. Synchronous & Asynchronous Communication To sum up synchronous communication it is when interaction with data takes place it is done in real time. On the other hand asynchronous or delayed communication is when any data which is archived or stored and accessed later. It is important to choose the most effective delivery mode because it directly impacts the level of interaction that is going to take place. Synchronous It does not use start or stop bits but instead it synchronizes the transmission speed with receiving and sending end of transmission using the clock signals specifically built for each of the components. After this constant streams of data are transmitted between two sources. Because no start or stop bits are involved data transmission is faster, but more problems occur because if latency takes into effect then the synchronization clock will be out of timing therefore the receiving node will get the wrong timings that have been acknowledged in the protocol sending and receiving data. If this happens then data can be corrupted, missing or even wrong message. There are ways around this which take time. You could use check digits and re-synchronize the clocks so that you can verify that the transmission has been successful and has not been interrupted. Advantages of using synchronous transmission are that lower overhead and more data can be transmitted and data transmission rates are al so faster. The drawbacks of using synchronous transmission is obviously more prone to problems, it is more expensive and more complex. Asynchronous Opposite to synchronous it uses start and stop bits to mark the start and end of a transmission, this means that 8 bit ASCII characters would be transmitted using 10 bits because the use of start and stop bits. For example (1)10111111(0) the bracketed out one and zero at the start and end mark the start and end of a transmission. This tells the receiving either the first character is transmitting or finished transmitting. This method of transmission is normally used when data is sent occasionally as opposed to in solid stream. Benefits of using asynchronous data is that it works out cheaper because timing is not that important and it is also simple because both end do not require synchronization. Drawback are that if a large amount of data is to be transmitted it would take a long time this is because a lot of bits are only for control uses they do not contain any useful information. Bandwidth is used to define how much volume a medium can transmit. Basically it is the maximum rate at which data can be transmitted across mediums. The more bandwidth a wire can handle the higher transmission rates can be achieved. It can also high transmission rates for multiple users. But there are restrictions in place such as if a user has been transmitting a lot of data between a period of time then a temporary limit will be put on. This is quite common with ISP’s. To stop this happening to you best thing to do is not to download a lot at the same time and also close programs which use the bandwidth continuously. Radio Transmission Radio is a way of transmitting signals using varied tones which convey a message of electromagnetic waves with a frequency. Electromagnetic radiation travels in direction of oscillating electromagnetic fields which go through the air and vacuum of space. Changes in radiated waves such as amplitude, frequency or phase allow information to be carried systematically. If the radio waves pass through electrical conductors the oscillating fields induce an alternating current in the conductor. This could be detected and changed into sound or any other type of signal which is able to carry information. Every radio system has a inbuilt transmitter this is the source which allows electrical energy that produces a alternating current of a desired frequency of oscillation. The inbuilt transmitter also has a system which changes some properties of the energy produced to impress a signal on it. This change could be as simple as turning the signal on or off. Change could be more complex such as alternating more subtle properties such as amplitude, frequency, phase or combination of all three properties. The modulated electrical energy is sent via the transmitter to an antenna. Antenna changes the alternating current electromagnetic waves; this allows the waves to transmit in the air. There are drawbacks of using radio. First is attenuation can happen, this basically means the longer the wave has travelling to get to its destination the more weaker it gets. Most obvious example of this would be someone listening to FM radio in the midlands; the further he goes away from the midlands the more signal gets weaker. Microwave An electromagnetic based wave which has a range or wavelength of up to 30 GHz. Currently microwaves are getting more popular due to advancing technologies. Microwave offers high bandwidth at low cost. Most common problem with microwave transmission is reflection. Microwaves are common used for radar which pickup planes and helicopters flying in the air. Microwaves will hit the plane or helicopter and reflect back and gets calculated giving the position of the flying object. Waves are reflected due to a barrier which stops the wave from going further so it hits the barrier and reflects back. Reflection affects the signal if the reflection is not good then the reflection won’t happen therefore a dead or a blank signal will be received. To minimize the effect try staying close the satellite. Wireless protocols such as Bluetooth use microwaves to transmit. Satellite Satellite is a orbiting piece of hardware which has been left floating in the air from big companies like Microsoft, satellite can be used for communication. There are also other types of satellites which are used for spying or used for online maps such as Google maps, Microsoft live maps or another services. Satellites provide high bandwidth solutions. Satellite is categorized as a WAN because it uses high speed & long distance communication technology which allows them to connect to computers. Attenuation also affects satellite connection due to the same reason. If a satellite is not in the required position and starts transmitting signal it will not reach television so they might not work properly or correctly. Satellite dish has to be in the same direction as the satellite. Satellite signals reach television using a transmission antenna which is located at an uplink facility. The facility has an uplink satellite dish which would be around 9-12 meters in diameter. The bigger the diameter of the satellite the more accurate signals and better signal strength from the satellite is received. The satellite dish would be pointed towards the satellite and the uplinked signal is received by the transponder at a certain frequency. This frequency is normally C-band (4-8 GHz) or KU-band (12-18 GHz). The transponder then retransmits the signal back to the earth. NTSC, PAL or SECAM are three broadcast standards used through out the world. NTSC is normally used in the US, Canada, Japan, Mexico, Philippines, South Korea and other countries. PAL which stands for Phase Alternating Line is an colour encoding system which is used by over 120 countries in the world. In a few years time most of the countries will stop using PAL and either change to DVB-T SECAM It is sequential colour with memory is the analogue colour television system. SECAM was Europe’s first colour t elevision standard and France currently uses it. The analogue signals for the three broadcasting types are transmitted via a satellite link scramble or unscramble. The analogue signal is a frequency modulated and transformed for a FM to something called baseband. The baseband fuses the audio and video sub carrier. The audio sub is further demodulated to provide a raw audio signal. Digital TV’s that transmit via satellites are normally based on open standards such as MPEG and DVB-S. MPEG which stands for Moving Pictures Experts Group is a compressed format which code moving pictures and associated audio information. There is also MPEG 2 which is a digital television signal which is broadcasted via terrestrial cable and direct broadcast satellite TV systems. DVB-S which stands for Digital Video Broadcasting is a standard for satellite TV’s which forward error coding and modulation. It is used by every single satellite that serves a continent. Standards Organizations There are difference types of standard organizations. These are the various types of standard organizations TIA/EIA, RS-232, IEEE, ISO, OSI and Manchester Encoding. ISO/OSI – International Standards Organization’s Open System Interconnect (ISO/OSI) is the standard model for networking protocols and distributed applications. ISO/OSI defines seven network layers. 1. Physical 2. Data Link 3. Network 4. Transport 5. Session 6. Presentation 7. Application I will be only be explaining in-depth the first network layer: Physical. This layer defines what cable or physical medium to be used. There are lots of different types of cable thinnet, thicknet, TPC, UTP. All of these mediums are functionally the same. The major difference between the various cables is the cost, convenience, installation and maintenance. Converters from one media to another operate at this level. TIA/EIA – Telecommunications Industry Association & Electronics Industries Alliance (TIA/EIA), state the standards which should be used laying cables in a building or a campus. TIA/EIA describes how a hierarchical topology should be laid out. A system where a main cross connect system is used and connected using a star topology using a backbone cabling through a intermediate or a horizontal cross connect. This type of cabling or similar is also used for laying out telecommunication cables. The backbone cabling method will be used to connect the entrance facilities to the main cross connect. In areas such as office a horizontal cross connect for the consolidation of the horizontal cabling, which extends into a star topology. Maximum stated horizontal cable distance should anywhere between 70M-90M. This applies to TTP (Twisted Pair Cable), but the fibre optic horizontal cabling has a set limit of 90M. IEEE – Institute of Electrical and Electronics Engineers allows the development of â€Å"Electro Technology† which in other words applies to electricity applied to technology. Societies like the IEEE Computer Society are subsidiaries of the IEEE itself. This standards organization also publishes journals. Devices such as digital camera need set amount of bandwidth speed so it uses a IEEE plug. Any device that uses the IEEE standard uses a twisted pair cable. Signalling Standards NRZ- It stands for Non Return to Zero. It is a binary code normally used for slow speed synchronous and asynchronous transmission interfaces. Ones is represented as a small voltage and zero is negative voltages. They are transmitted by either by set or constant DC voltages. It also uses additional synchronisation so it dose not lose any bits in the process. NRZ-L – Non Return to Zero Level is similar to NRZ, but it not a binary code. Same as NRZ one is represented as small voltage, but zero is also represented as a small voltage but it is not as big voltage as one, Therefore it allows more data to be send without a lot of signal change. NRZ-M – Non Return to Zero Mark again similar to NRZ, but one is actually represented by a change in physical state and zero is represented as change in physical state. This basically means that there is no voltage when there is no change in physical state. RS-232 – This standard applies to serial data transfer such as the 9 pin serial connecters which are commonly used on a computer motherboard. The data is sent in as time series of bits. Synchronous & Asynchronous is both supported by this standard. This standard and states the number of control circuits that can be or need to be used to connect the DCE & DTE terminal with one another. Data and control circuits which are signalled from a DTE connected to a DCE or vice versa will always flow and operate in one direction this is called half duplex. Only full duplex allows data to be sent and received in both directions at the same time. Manchester Encoding – Data bits which are represented by transitions from a logical state another is called Manchester encoding. This is a digital type encoding. In this encoding the signal is self clocking because the length of every data bit is set by default. Depending on the transition direction the state of the bit can be analyzed. In Manchester encoding the signal synchronizes itself. This is an advantage because this will decrease the error rate and optimize the reliability. But on the other hand it is also a disadvantage because the amount of bits sent in the original signal when transmitted has be twice the amount of bits from the original signal. Differential Manchester – Also known as Conditioned Diphase (CDP). It is a encoding method which uses data and clock signal as fused to create a self-synchronizing data steam. Similar to Manchester encoding it uses present or absent transitions to represent logical value. TTL – Transistor Transistor Logic is a binary code which either uses high voltages between 2.2V and 5V to represent one and no voltages between 0V and 0.8V to represent a zero Name Specification Maximum Length/Speed Advantages Disadvantages Cat.5 Cable RJ45 Connector.

No wires needed and very long distances capable. Signal gets weaker the more time taken to reach the destination. Security is a problem very open for hackers. LAN This is type of network which covers a small office, home or a school network. A LAN uses either wired Ethernet or wireless RF technology. Using a LAN can be much easier when there is a printer available or sharing a file throughout the network. Updating software is much easier because updating software will automatically update all the other software’s. LAN has much higher transmission rates because it is wired connection rather than wireless. Ethernet and Wi-Fi as most widely used technologies, however many others such as token rings have been used before. This relates to standard IEEE 802.2. This standard allows two connectionless and one connection orientated operational mode: Type 1 which allows frames to be sent to a single destination or multiple destinations on the same network is a connectionless mode. Type 2 is the oriented operational connection mode. In this mode it uses something called sequence numbering which makes sure that when the data is send it gets to the destination in the correct order and not a single frame has been lost. Type 3 which is also a connectionless service, but only support point to point communication. Infrared is related to this service because in computer infrared network it can receive and transmit data either through the side of the device or the rear side of the device. When connections are made using Microsoft Windows Infrared the same method used for LAN connections can be used. Infrared technology has been extended to allow more than two computers to be connected semi permanent networks. The advantage of a LAN is that the same physical communication path can be shared by multiple devices. For example it there is a printer, a computer and the internet connection the LAN will allow connections to the printer and it will also allow connections to the internet. If a software is loaded onto the file server that all the computers on the network can use it. There are quite a few drawbacks of a LAN network. For example security measures need to be taken so that users cannot access unauthorised areas. It is quite hard to setup the network. Skilled technicians are needed to maintain the network. Yet the biggest disadvantage is that if the file server goes down than all the other computers on the network are affected as well. WAN This type of network covers a wider area. It is used over high speed, long distance communications such as computers in two different areas. A WAN can also be shared. For example two occupants in two buildings can share the wireless connection to a third person, or a business or anyone or anything they wish to do so. Data is safe, secure and quick when it is transmitted between two computers. WAN can also be used to connect different types of networks together for example a WAN network connected to a LAN networks. The reason behind this is that it is AppleTalk. It is a cheap LAN architecture which is a standard model built for all Apple Macintosh computers and laser printers. It also supports Apple LocalTalk cabling scheme as well as Ethernet and IBM token ring. AppleTalk can connect to standard computers which do not have AppleTalk. This all relates to FDDI standard which stands for Fibre Distributed Data Interface. It is a backbone of a wide area network. It uses fibre optic cable to transmit data up to supported rate of 100 Mbps. An advantage of a WAN it allows secure and fast transmission between two computers. Data transmission is inexpensive and reliable. Sharing a connection is easy as well because it allows direct connectivity. A WAN also allows sharing of software and resources to other workstations connected on the network. Disadvantage of a WAN network is that the signal strong all the time so anyone trying to hitchhike a connection can use the WAN connection it is not protected. WAN are slow and expensive to set-up. They also need a good firewall to stop intruders using the connection. Networking Mediums Different types of medium are used for different types of topologies. Coaxial Cable It is normally used to connect telecommunication devices which used for broadband connection which use high transmission rates to transfer data. The cable is insulated using a braided shield which is also known as a screen. It protects the cable from electromagnetic interference. It has higher capacity than a standard copper wire. Therefore it allows radio frequencies and television signals to be transmitted. Various types of coaxial cables are available which can be used for thin Ethernet which are used for networking 10Mbps connections lengthening up to 200 meters. There is also thick Ethernet cable is also used for 10Mbps connections but stretching up to 500 meters. Unshielded Twisted Pair (UTP) coaxial cable has been used in the past when building networking using thick or thin Ethernet. Ethernet cables quite expensive but they are still used because they carry more data then a telephone wire and it is less susceptible to interference. Optical Fibre Optical fibre also known as a fibre optic cable uses light to transmit data. Light is made using a laser or LED is sent down a fibre which is thin strand of glass. Fibre optic is about 2 microns in diameter which is 15 times thinner than a single human hair. Optic fibre is not affected by electromagnetic interference. It is cable of higher than data transmission rates, ideal for broadband usage. Fibre optics are manufactured in two different types the single mode and multi mode. The difference between the two is quite obvious single mode uses one beam of light to transmit data to longer distance of around 3 km but the multimode uses multiple beams of light to transmit data but only to shorter distance of 2 km. This allows more data to be sent simultaneously. It is normally used for broadband transmission as mentioned before because it is faster at transmission than any other cable currently available. Fibre optic also has an advantage of long distance transmission because light propa gates through the fibre with little attenuation compared to electric cables. Not many repeaters are needed for long distance. Data travelling using the fibre can reach rates of unto 111 Gbps. Fibre optics also restrict high voltages travelling from end to end of a fibre to another end. It also restricts cross talk and environmental noise between signals transmitting to different cables. UTP (Unshielded Twisted Pair) & STP (Shielded Twisted Pair) UTP and STP both use copper wires which are known to man as one of the oldest types of transmission media methods. STP is insulated with a metallic plastic foil which is all under the plastic sheath. This insulating is expensive to make that’s why it is more expensive than normal cable. Even though STP cable is shielded there is still crosstalk. It cannot be eliminated. Both UTP & STP individual wires are twisted together so it creates there is less crosstalk. Core of each of the type of cable is a very good conductor and easy to work with. Media which can be used with UTP is internet, because it is easy to install, maintain, less expensive and allows higher transmission rates. The media used with STP is also internet, but it is more expensive and difficult to install. The advantage is that there is less interference. It is difficult to install because it has to be grounded at both ends. Improper grounding will result I metallic shielding acting as a antenna and it will pick u p unwanted signals. Due to the cost and difficult to install and maintain it is hardly used in Ethernet networks. It is mainly used in Europe. Crosstalk Crosstalk means that signal that are transmitting in different circuits interfering with each other. Crosstalk happens because unwanted signals interfere with another channel transmitting undesirably. Electrical Noise Noise is when an electrical signal is transmitted across a wire which is not the sent signal by the user, but it is another signal which has been picked up randomly. Twisted pair cables eliminate the interference because they are twisted with each other so they cancel out each other. The thickness and varied insulation of a cable and its capacitance of the wires will cause noise. For example when there is communication on a telephone and either person cannot hear the message clearly this is caused by noise affecting the signal. This is known as crosstalk, as mentioned before crosstalk is when signal is affected by electromagnetic field around a wire. Electric noise cannot be eliminated but can be minimized by taking caution. Keep cables away from electrical equipments and shield the cable weather it is a fibre optic or a STP. Checksum It is a method used for error-checking the received data against a calculated checksum. For example when a data is received by the designated node the checksum error detection method will create a new calculation and check it against the old calculation to check weather the same result it received. This makes sure the data has not been altered in any way when it was transmitting. The checking of the data is called checksum function or checksum algorithm. Cyclic Redundancy Check (CRC) CRC is another type of error-checking technique used in data communication. A CRC character is generated at the end of the transmission. The produced CRC character’s value depends on the hexadecimal value of ones in the data block. The node receiving the transmission makes a similar calculation and compares it to the source node and it the values are different then it asks for retransmission of the data. Frame It is a collection of bits sent over a medium. It contains physical address and control information. It also contains error-detection methods like CRC. The size and role of the frame is all dependent on the type of protocol, which is often used synonymously with packet. When the data is split and if necessary it is sent to Ethernet frame. The size of the Ethernet frame varies between 64 and 1,518 bytes. It uses the IEEE 802.3. It contains address, length, data and error checking utility. The data is passed onto the lower level components corresponding to OSI’s Physical layer. This converts the frames into bit-stream and sends it over the transmission medium. Other network adapters on the Ethernet receive the frame and analyze it for the destination address. If the destination address match of the network adapter, the adapter software simply processes the incoming frame and the passes the data to higher levels of the protocol stack. Packets It is a unit of data sent across networks. When a computer transmits data it will split or divide it into packets when it reaches the defined node it is transformed into the original transmission. Also known as a datagram it contains two parts. The header which acts as a envelope and the other part is the payload which is contents. Any message sent over the size of 1,500 bytes is fragmented into packet for transmission. When packet filter is put into place the header of incoming and outgoing packet is analyzed and decides whether to let them pass or restrict the packet, this is decided based on network rules. Data Transmission Modes & Methods There are three different ways transmission can take place. Data transmits either using simplex, half duplex or full duplex mode. There are two different ways how data is transmitted. Data can be transmitted via serial or via parallel transmission. Simplex Simplex data can only travel in one direction. Television and radio broadcasting are example of simplex. Fibre optic works with simplex mode. Simplex is good for satellite communications. TV signal is the proof that satellite communication is good because the transmission is good and clear. Simplex is rarely used for computer based telecommunications. Half Duplex Half duplex data can travel both ways but only in one direction. Coaxial cable works in half duplex mode. Radio is a example of half duplex because the signal reaches the destination and comes back to the original source. Communication between networks also works at half duplex. If a node is transmitting a message and another node wants to transmit it has to wait till the token ring comes back. Full Duplex In full duplex data can travel in both directions and at the same time. The bandwidth is divided in both directions. UTP/STP mediums work at full duplex. For example Bluetooth is a full duplex because data can be received and sent by both devices. Another example is landline telephone because both end of the phone can speak and listen to each other. Serial Transmission In serial transmission one bit is sent at a time. It is good for communication between several participants. Serial transmission is slow. When the data is sent it is dissembled by the source and reassembled by the receiver. Parallel Transmission Parallel transmission is when every bit is sent simultaneously but using separate wire. Basically when data is parallel channel transmitted for i.e. 8 bits or a byte everything is sent simultaneously therefore it’s faster than serial because serial channel would send the 8 bits or byte one by one. Most common example is communication between a printer and the computer.
