Circuit Switching and Packet Switching Essay Example for Free

Circuit Switching and Packet Switching Essay Circuit switching, although more reliable than packet-switching because it is able to get your message across without any hiccups, is old and expensive. Circuit switching is based on having a dedicated line or session between two stations and thus, you are able to get the full message across without congestion or interruptions. An example of circuit switching hardware is PBX. In addition, with circuit switching, a path to the destination is already decided upon before the transmission starts and it only terminates once the session is complete and sends its message through. A disadvantage of circuit switching is that you are only able to use the line or transmit one session at a time because of its dedicated circuit. Another disadvantage is its cost. Packet switching is more modern and transmits voice data. Although, as compared to circuit switching, the quality may be lower because of the ability to use lines or sessions at the same time and thus, creating congestion or even data loss. With packet switching there is no circuit dedication like circuit switching. However, unlike circuit switching where the path to the destination is already decided upon before transmission, with packet switching, each packet has to find its own route to the destination. The disadvantage of packet switching is the potential for low quality transmissions and even data loss. In my opinion, these days, packet switching is more commonly used because it is used in LAN technologies or set ups. I would think that circuit switching is used for analog lines and networks, but during these days where most organizations are changing to digital and especially VoIP, packet switching would be more common.

The Evolution of Minorities in Film Essay -- Movie Film Essays

The Evolution of Minorities in Film Back in the 1800’s, when calculating the population, African Americans were counted as 3/5 of a person (Antonia, p2). One would think that in the past two hundred years people’s beliefs would have changed a little bit, but the general white public are stuck into believing the common stereotypes commonly portrayed in movies. In films and television shows blacks are almost always portrayed as murderers, robbers, rapists, pretty much anything negative, like American History X, for example. Two black men are shown breaking into a white man’s car. People see this, and in turn believe that all black men will try and steal their car; as stupid as it may seem, it is true, and as a result, film producers try to incorporate this into their films. Very rarely, if ever, is it possible to see a minority depicted as a hero-type figure. Every once in a while, there will be an independent film from a minority director, but as Schultz states in Lyon’s piece, â€Å" We [blacks] are still being ghettoized in Hollywood, a serious black project of any scope is as difficult to get marketed today as it was in the ‘70s.† By making a barrier to entry for minorities in the film industry, it’s almost as if America is trying to keep black films out of the popular media. At first glimpse, it may appear that minorities are very hard to be seen in the filming industry, when in reality, they are becoming more and more apparent in America’s mainstream media culture, particularly in action movies. MacDonald stated in Allan Smith’s essay, â€Å"American mass culture continued to operate as an assimilative force, seeking to maintain social stability while gradually merging people of different backgrounds into the cult... ...ral trend of how minorities are making a bigger and bigger impact on American mainstream culture. All America can do is smile and be content at the fact that minorities are finally getting the respect they deserve.    Works Cited    Antonia, Kathleen. â€Å"A Lesson Before Living† Humanist, March/April 2001, Volume 61 Issue 2, p.43.    Beck, Bernard. â€Å"What Price Glory?† Multicultural Perspectives, 1999, Volume 1 Issue 1, p.26.    Brinkley, Douglas. â€Å"Edward Norton’s Primal Fear† George, October 1998, Volume 3 Issue 10, p.110.    Lyons, N.L. â€Å"From Race Movies to Blaxploitation to Homeboy Movies† American Visions, February 1992, Volume 7 Issue 1, p. 42.    Smith, Allan. â€Å"Seeing Things: Race, Image, and National Identity in Canadian and American Movies and Television† Canadian Review of American Studies, Autumn 1996, Volume 26 Issue 3, p. 367.

History †The American Revolution Essay

Throughout the colonial period, there were many factors that led to the Revolutionary war, and it was when Britain began passing increasingly oppressive restrictions that colonists began to see independence as the only alternative to British rule. More than anything else, the actions of the British government fostered the feelings of nationalism in the loose collection of isolated colonies. There were many classical examples of British encroachment against liberty in the eyes of the colonists. After the French and Indian War, Britain changed its policies regarding the colonies. These changes in policy, especially the British attempt to raise revenue through direct taxation aroused resentment and in the colonies. Because of the war, Americans gained self-confidence and military experience, saw the need for colonial unity to meet common problems, and had the danger of attack by the French and certain Indian tribes removed from their frontiers and thus become less dependent on Britain. The British policies enacted were meant to place the colonies under strict British political and economic control, compel the colonies to respect and obey British law, and make the colonies bear their part of the cost of maintaining the British Empire (Gordon, 1993). The series of British decrees that followed faced strong opposition in the colonies and did little but encourage nationalism. The Navigation Acts and Writs of Assistance greatly hindered the colonists’ freedom to pursue maximum profit from their labor, as well as freedom from unfair searches by British authorities. No single act did more to unify opposition to imperial rule as the Stamp Act, which led directly to colonists taking the name of â€Å"Patriots† to show their solidarity and opposition (â€Å"The American Revolution: Causes and Consequences,† p. 4). The Stamp Act was the first internal tax levied on the colonies and negatively affected influential lawyers, clergy, and printers, who would increase the sense of national unity and opposition to the crown. The Townshend Acts were a new tax levied on colonial imports, and those colonists in violation were forced to submit to a military trial instead of trial by jury in colonial court (Gordon, 1993). The Quartering Act also imposed upon colonists to provide food and shelter to British soldiers. These taxes and acts, mostly designed to create subordination amongst colonists, had the opposite effect. Colonist began to protest, and delegates from nine colonies even created a Stamp Act Congress in 1765 to protest British tax and boycott British goods. With widespread opposition continuing to grow, the Boston massacre enraging colonists, and the Intolerable Acts coming as the final blow, the First Continental Congress was formed in 1774 and the first steps towards complete national unity had been taken (Gordon, 1993). By 1776, the colonists were ready for a complete break from Britain, no matter the costs, even war against a world power. Despite being untrained and outgunned, the American colonists enjoyed many advantages that enabled them to win the war. The colonies were separated from Britain by 3000 miles of ocean with contacts maintained only by slow moving ships. This slow and sometimes non-existent communication only widened the gap between the genteel British nobility and forces in America. Although most colonists were British in origin, their environment had transformed them into Americans, with intimate knowledge of the makeup of the land. Interaction with Indians, the often difficult North American environment, and the feeling of independence from home rule created a situation in which the Americans were simply more motivated and willing to fight than their British counterparts. Furthermore, many Americans had come from countries hostile to Britain, contributing to the anti-British sentiment. Finally, and perhaps most importantly, a small but highly active minority resented the British monarchy and desired independence which inspired the country to fight. Likewise, the British authorities failed to comprehend the seriousness of colonial resolve. King George III, seeking to revive executive power in Britain, considered the colonists ungrateful and disloyal, rejected efforts at compromise, and pursued a policy of suppressing the colony by force (Gordon, 1993). Presented with a harsh, growing opposition from Britain, colonists began to see themselves as something unique—Americans. Their European way of living was modified by the American environment, especially the frontier with its great tracts of available land, its danger from the Indians, and its challenges from Nature. In adjusting to the new environment, the colonists were forced to change and it only aided their separation from British rule. They developed a spirit of individualism, self-reliance, independence, and faith in the future. With the passing of time, a new person emerged that was no longer a European, but an American in character and outlook (Gordon, 1993). This independent spirit did echo many of the ideals that encouraged British peasants centuries earlier to challenge the monarchy for increased rights, and may have been inevitable. The former British quest for independence saw the creation of the Magna Carta, Parliament, the passage of English Common Law, and eventually the English Bill of Rights during the Glorious Revolution of the late seventeenth century. American desire for self-rule and democracy was uniquely British in that regard, and the distance from the kingdom allowed the colonists to actively seek full independence in a way that the British common man could not. And, through perseverance and high ideals, the colonies succeeded in uniting to defeat their common enemy and create the United States of America.

How Learning Styles Can Improve A Persons Way Of Learning

According to the Merriam-Webster dictionary, â€Å"learning is the activity or process of gaining knowledge or skill by studying, practicing, being taught, or experiencing something.† Referring to the textbook, Life-Span Human Development, 7th edition, by Carol Sigelman, on page 244, â€Å"memory is our ability to store and later retrieve information about past events, develops and changes over the life span.† In this essay, I will be discussing how learning styles are implemented in our memory to help us later recognize information that we had processed through specific styles of learning. Through different online tests that I have recently taken, I will explain how different learning styles such as visual, auditory, and tactile learning can help improve a person’s way of remembering subjects, also defined as memory. Not long ago, I took two different types of learning style tests. The first test that I took was through the website, www.educationplanner.org. Acc ording to this website, my results concluded that I was a tactile learner. Referring back to the questionnaire, What’s your learning Style? 20 Questions, â€Å"a tactile learner learns by touching and doing. They understand and remember things through physical movement. They are a ‘hands-on’ learner who prefers to touch, move, build, or draw what they learn, and tend to learn better when some type of physical activity is involved.† I agree with the statement that I could possibly be a tactile learner because I make a lot of handShow MoreRelatedContinuing Academic Success1112 Words   |  5 Pages and advancements that are being made in their area of employment.
