The Ethernet Technology Report - Essay Example For transporting digital bits of data through the carrier waves, Ethernet has some encoding techniques. These encoding techniques aid in synchronizing the data sending and data receiving stations and providing a signal with strength sufficient enough to deliver a required amount of data rate. So, the difference in encoding techniques relate to the difference in the data transfer speed provided by the Ethernet cable. For instance, the three encoding techniques Manchester, 4B/5B and 8B/10B are used for the providing Ethernet LAN of speeds 10Mbps, 100 Mbps and 1Gbps respectively (TechFest.com, 1999). Manchester encoding delivers a signal of frequency 10MHz which is sufficient to provide a data rate of 10Mbps for the 10Base5 and 10Base2 coaxial cables. The installation is easy and new systems can be added easily. However, owing to the bus topology (in 10Base5) and the fact that the cabling is half duplex (i.e. same cable used for sending and receiving), chances of collisions would be mor e and the throughput of the system would be less. In case of daisy chains (10Base2), routing difficulties would be present. Secondly, the higher data rates cannot be achieved due to coaxial cables. In case of using 10BaseT twisted pair cables, 20Mbps can be achieved owing to full duplex mode. New hosts can be added easily in the supported star topology network. However, repeaters are required after every 100m unlike 10Base5 and 10Base2. When using 10BaseFL, repeaters are not needed till 1000m. The 4B/5B encoding delivers a 62.5MHz frequency signal on the 100Base-Tx Cat 5 twisted pair cabling. A signal of maximally 100MHz is enough to be transmitted over a medium of 100Mbps. In full duplex mode, any new host can be added without affecting the collision rates. 4B/5B encoding is also used in 100Base-Fx cables.

Short reaction on Casablanca 1942 - Essay Example me even more popular over the years, lies in the fact that since 1957 many cinemas began to show the movie during summer exams, first in Harvard, and then and in other universities. Twenty years later it was revealed that Casablanca is shown on TV in the USA more often than any other movie in order to attract the new audience (Ebert, 1996). The movie is sensitive, kind, magically romantic and very fascinating, though it is neither thriller, nor the detective story.

Slumdog Millionaire Essay Example for Free

Slumdog Millionaire Essay The issue we have decided to discuss is centred around the two children Rubina Ali and Azharuddin Ismail who star in a leading role in the film Slumdog Millionaire. The film grossed $141,000,000 in the US alone and had a budget of $15 million but the two children only received  £500 ($700 American Dollars) and  £1,700 ($2408.50 American Dollars). Despite the claims of director Danny Boyle, that the film has â€Å"completely changed their impoverished lives† (Tyler, 2009) the children continue to live in the slums in India from where they were originally found. The children’s parents were very disappointed given the films worldwide success and had hoped that this film and their children’s leading roles would have given them opportunity of a better life outside the slums. Having found themselves leading the same lives as before Slumdog Millionaire, they realised just how under-paid their children were actually paid. Ismail predicament is considerably worse off as his illegal home was recently demolished by local authorities. It is even more difficult for the children to return to the slums given the lifestyle and the luxuries they received during the filming, promotion and subsequent award ceremonies. However both film makers and film distributors have disputed the families’ claims and have highlighted that the wages paid to both the children were three times the average local annual adult salary. Furthermore provisions have been made for the children’s education and once completed a trust fund will be paid to the then 18 year olds, Ali and Ismail. Ethical issues surrounding the topic * Underpaying the child actors in the Slumdog Millionaire movie * Allowing the children to return to the slums * Returning the children to their poverty stricken roots having experiences the lifestyle of a movie star * Not providing the children with a place to live after their home had been destroyed * Is the trust fund achievable given the children’s circumstances and harsh living conditions?

The Watergate Scandal :: President Richard Nixon

The Watergate scandal had everything. Nixon disgraced the presidency by lying to the country and abusing his power and his committees were involved in illegal acts and a big cover up, all leading to little side roads of corruption and lies. Watergate is by far one of the worst presidential scandals in the history of the United States. In the story of Watergate, five burglars were found breaking into democratic offices at the Watergate complex in Washington DC. The break-in was passed off as just another burglary, but when the burglars were found to have connections with the CIA, questions were starting to be asked. Then when the phone number of Howard Hunt was found in one of the burglar’s phone books, it made people think, why would one of the burglars have the phone number of one of the presidents men? When Watergate was uncovered, it revealed that the president was a liar and a cheat. The president lied to our country, lied about his involvement, concealed self incriminati ng evidence, abused his power, and planed to have the CIA stop the FBI investigations. During the times of the unraveling of Watergate, questions were asked about connections with the White House and the president, but when the president was asked about it at a press conference he assured Americans that The White House has no involvement whatever in this particular incident. The lying and cover-ups did not end there, it went on and on for months, and as the scandal kept unraveling, President Nixon and White House, and CREEP officials were deliberately misleading the public about the significance of the Watergate affair. As Watergate was becoming a front-page article in the newspapers, new evidence was being uncovered. One piece of evidence that changed the peoples’ ideas of our president was the tapping of every conversation in the oval office since about the 18th month of President Nixon's term. Those tapes would soon prove that the president was deeply involved in the scandal. The Nixon tapes brought out much controversy. The tapes alone could prove the president innocent or guilty, but whichever one it was, Nixon refused to hand over the tapes. After much struggle Nixon agreed to give a transcript of the tapes. The transcripts brought to light a significant amount of evidence against Nixon. The transcripts revealed payoffs, affiliation with the burglaries and the OK's to the cover-up, but most important the transcripts showed that Nixon had lied repeatedly after he had denied knowing anything about the conspiracy.

Philippines: The National Achievement Test Essay

To assess and monitor the quality of basic education in the Philippines, achievement tests were administered to public schools both elementary and secondary. These achievement tests include National Achievement Test (NAT), Regional Achievement Test (RAT) and Division Achievement Test (DAT). Of these three achievements tests, the NAT is the main criterion of the school performance. Meanwhile, the RAT and DAT served as preparatory assessment procedures to be able the school to determine its readiness for the |NAT. The National Achievement Test (NAT) is a Philippine-made standardized test designed to determine pupils/students’ achievement level, strengths and weaknesses in five key curricular subject areas at the end of the school year.

The women of ancient Sparta were a striking exception.

The Great Gatsby By F. Scott Fitzgerald - 1398 Words

â€Å"To do two things at once is to do neither†(Syrus). As Publilius Syrus suggests, in an age where multitasking is more common than the ideals concencentration, it is important to reconsider the capabilities of man. The idea of taking on multiple tasks underlines man’s capabilities in that it often gears the mind in two opposite directions with equal power. In this regard, though it may seem efficient, it is actually vile for man to attempt to sustain multiple projects that gear toward opposite directions. This idea is confirmed by F. Scott Fitzgeralds’ The Great Gatsby, a novel in which the protagonist Jay Gatsby illustrates why man isn’t capable of taking on two equal and opposite projects at the same time. Gatsby fails to conquer Daisy†¦show more content†¦Ã¢â‚¬Å"They’re a rotten crowd,† I shouted across the lawn. â€Å"You’re worth the whole damn bunch put together†(Fitzgerald 154). Far beyond hierarchy, there i s character. Gatsby, well known for his reserved nature doesn’t fit into the life of Daisy Buchanan. She is a â€Å"rotten†, careless woman and as Nick points out Gatsby is something else. He is full of heart. He is a thoughtful person who associated himself better with the lower class than the upper class. Gatsby’s only fault is that he is torn by the power of the upper class while trying to obtain Daisy. In much the same manner, Gatsby later shows off how his character is impossible to hide despite his wealth. As he wishes to meet up with Daisy again, he refuses to employ his power to seek her. Jordan reveals the cause of her surprise earlier, â€Å"It was that night he sent got me at his dance, and you should have hear the elaborate way he worked up to it. Of course I immediately suggested a luncheon in New York-and I thought he’d go mad: â€Å"I don’t want to do anything out of the way! he kept saying, ‘I want to see her right next do or.’(Fitzgerald 79). Gatsby is powerful person, he gets what he wants, when he wants it. One thing is clear though, he doesn’t think the same way as the rest of his fellow high-class friends. He doesn’t stand for any drama, or attention from people, but rather he remains the same introverted person who hopes to find Daisy in a private manner. Gatsby doesn’t
