...Two backbone configurations could be Cable Modems and a FIOS. It is used for transmission or receipt over cable television lines, and is is used primarily for connecting to the Internet. A cable modem converts analog data signals to digital form and vice versa to transmit signals over cable lines much faster, and it is not to be confused with a telephone modem. Transmission rates average around 1.5 mbit/s. Because cable is shared among multiple tenants, connection is usually slower during the hours most users are on the internet. Faster transmission is actually possible, but in addition to shared overload, speed can usually be restricted by the cable company’s connection to the Internet. Cable Internet access is competitive with DSL. * PROS: Fast for the value * CONS: Initial cost and limitations of available locations. FiOS FiOS stands for Fiber Optic Service that connects to the Internet using light over an optical network. In your home, you still connect your computer through copper wiring. The advantage of FiOS is that it can provide higher speeds than traditional copper wire connections such as DSL or cable. Some Internet providers offer multiple options, depending on the area you are in. More populated areas are more likely to have FiOS available. Check with your phone company or Internet provider for more information. * PROS: operates at speed of light * CONS: limited to one provider (Verizon) and not available in all areas Of course, a lot depends...

...Rumspringa is the time Amish children decide whether they want to be Amish or not. Rumspringa begins when the Amish turn 16 years old. Amish children tend to get real drunk on their 16 birthdays. In addition, some of them start to smoke during that period of their life. People tend to wonder how rumspringa encourage deviance, but in my opinion, when a young person decides to be disorderly and participate in deviant behavior they are making a choice of their own. When teenagers decide to take drugs, not follow the law, be violent or behave in ways that society do not approve of that can be classified as deviant. From the ages 16 and over, Amish children have to make a decision between following Jesus Christ or not because that’s know as an accountable age. I believe, that the children should not have to be pressured in to making such a difficult decision. People should be able to choose whatever paths they want to do in their lives at anytime. When the Amish decide to become Christian and baptized they are promising God that they are going to obey rules and regulations of the church. In which, I believe is very difficult because their lives are revolved around church and their little community, the Amish segregate themselves from the modern world. They do not used electricity and they create everything from scratch. The Amish do not own a Television, phone, car and more. During Rumspringa, the Amish youth tend to get cars and drive them around instead of riding on a horse wherever...

During the age of sixteen Amish kids enter Rumspringa period, where they been given the opportunity to discover themselves and decide to choose the path they want to move on. During this period, Amish kids are free to do what they want to do i.e. smoking, drinking, drugs and all the other luxury things of outside world. The Rumspringa period ends when individuals feels ready to make a decision if they want to join the church and obligate to being Amish or they want to join the outside world away from their family and religion. Most of the kids are able to decide around age of...

Network neutrality is the idea that Internet service providers must allow customers equalaccess to content and applications regardless of the source or nature of the content.Presently the Internet is indeed neutral: all Internet traffic is treated equally on a first-come, first-serve basis by Internet backbone owners. The Internet is neutral because itwas built on phone lines, which are subject to ‘common carriage’ laws. These lawsrequire phone companies to treat all calls and customers equally.

...Lab 1: Evaluating Internet Connection Choices for a Small Home PC Network Objective This lab teaches the basics of using OPNET IT Guru. OPNET IT Guru’s user-friendly interface with drag-and-drop features enable students to effectively model, manage, and troubleshoot real-world network infrastructures. We investigate application performance and capacity planning, by changing the link speed between a home LAN and its ISP. Overview OPNET’s IT Guru provides a Virtual Network Environment that models the behavior of networks, including its routers, switches, protocols, servers, and individual applications. The Virtual Network Environment allows IT managers, network and system planners, and operation’s staff to more effectively diagnose difficult problems, validate changes before they are implemented, and plan for future scenarios such as traffic growth and network failures. You can do “what if” analyses (called scenarios in IT Guru) on network designs, just as you can on spreadsheets with financial business models. However, instead of looking at “bottom line” financial numbers, you will be looking at how response times, latency (delays) and other network performance measures will change under different network design approaches. To create a network simulation (called a project in IT Guru), you specify the nodes (computers, switches, routers, etc.) in your network, the links between nodes, and the applications that will be running on the nodes. In this exercise, the initial simulation...

O’BRIEN 2010 THE LIABILITY OF INTERNET SERVICE PROVIDERS FOR UNLAWFUL CONTENT POSTED BY THIRD PARTIES By N.D. O’BRIEN Submitted in fulfilment of the requirements for the degree of MAGISTER LEGUM in the Faculty of Law at the Nelson Mandela Metropolitan University January 2010 Supervisor: Prof F. Marx PREFACE I would like to extend my thanks to the following people: To my parents and Emma Taggart for their help, encouragement, sacrifice and support; To my supervisor, Prof Marx, for his assistance and guidance; To Dawn Prinsloo, at the NMMU Library, for providing me with her time and guidance; To Ms. Fourie, the Law Faculty Officer, for her always prompt and friendly assistance; To Mr. Ant Brooks and the Internet Service Provider Association, for providing me with a variety of interesting information and insights. Without their invaluable assistance I would not have been able to have completed this work. i SUMMARY Internet Service Providers (ISP’s) are crucial to the operation and development of the Internet. However, through the performance of their basic functions, they faced the great risk of civil and criminal liability for unlawful content posted by third parties. As this risk threatened the potential of the Internet, various jurisdictions opted to promulgate legislation that granted ISP’s safe harbours from liability. The South African (RSA)...

...1. Network neutrality is the idea that Internet service providers must allow customers equal access to content and applications, regardless of the source or nature of the content. Presently, the Internet is indeed neutral: all Internet traffic is treated equally on a first-come, first-served basis by Internet backbone owners. 2. Telecommunications and cable companies are unhappy with this arrangement. They want to be able to charge differentiated prices based on the amount of bandwidth consumed by content being delivered over the Internet. These companies believe that differentiated pricing is “the fairest way” to finance necessary investments in their network infrastructures. Advocates of net neutrality are pushing Congress to find ways to regulate the industry to prevent network providers from adopting Comcast-like practices. The strange alliance of net neutrality advocates includes MoveOn.org, the Christian Coalition, the American Library Association, every major consumer group, many bloggers and small businesses, and some large Internet companies like Google and Amazon. 3. Neutral Internet encourages everyone to innovate without permission from the phone and cable companies or other authorities, and this level playing field has spawned countless new businesses. Allowing unrestricted information flow becomes essential to free markets and democracy as commerce and society increasingly move online. Network owners believe regulation to enforce net neutrality will...

...,Compare and contrast the narrative structure of at least two of the films studied. Your answer should also evaluate the reasons why these structures were chosen. Since the commercial success of Alejandro González Iñárritu’s Amores Perros in the year 2000, there has been an indubitable resurgence in the amount of interest in, and amount of films being produced within Mexico. This picture, as well as Y Tu Mamá También (2001) by Alfonso Cuarón both received worldwide acclaim and have set a high benchmark for the other Mexican releases since the millennium to live up to. This essay will explore the prominence of narrative structure in the aforementioned Amores Perros (2001), as well as Amat Escalante’s Los Bastardos (2008) and Guillermo Del Toro’s El Espinazo del Diablo (2001). The constituents of a film’s narrative structure come under two different entities: the content of the film’s story, and the way in which the story is presented to the spectator. Vis-à-vis the content of the films story, the essay will mention how, on a thematic level, these films each rely heavily on the use of violence to delineate its message and intentions. James Kendrick states that the use of violence in a film is employed as a structuring device and it is evident that each of these films uses violence for differing intentions, of which the essay will later make discernible. Subsequently, the essay will contrast the order in which the stories are presented to the viewer, chiefly, regarding how Amores...

...that occur in his character as he struggles with his crucible. Also, I will analyze a crucible that I have faced. Hale grows almost exponentially throughout the duration of Act Four in The Crucible. On page 130, Hale is trying to convince Danforth to postpone the trials of the accused: “Excellency, if you postpone a week… that speak mercy on your part, not faltering.” After Danforth’s response, including a discussion of the trials doing God’s work in Salem, Hale speaks his mind again and announces that Danforth is mistaken in his judgment. At this point Hale begins to realize what he must do. He must attempt to delay, if not halt these trials, in order to prevent people from hanging needlessly. Hale shows outright maturation and grows a backbone, so to speak; he is finds strength and intensity from a will to do good. Hale continues to express his concern and feelings on the trials by making a personal statement directed at Danforth. He bluntly exclaims the present situation to the seemingly oblivious Danforth. There is an issue of orphans wandering the town, of crops dying and cattle roaming aimlessly. Hale makes it clear that this is a...

...Burj Khalifa Turner Construction Company Executive Summary Turner’s business philosophy is to work very closely with customers on all its projects. It strives to share the most up to date and accurate information with them. Thus, making customers a partner in the business risk and rewards. It also empowers its employees to record accurate information by decoupling individual bonuses from project performance and tying it to overall corporate performance. It has a well-structured management control system through Indicated Outcome Reports which help Turner to identify and manage not only the risks but also potential savings in the projects. We recommend that Turner could release $200,00 of C-holds and balance $300,000 from construction contingency. This is keeping in mind that it is a new customer and releasing the funds would help Turner in further nurturing the relationship. However, it needs to keep a close watch on scope enhancements being approved by owners and cost control. Turner: Background and Simon’s perspective Core Values Turner’s business model revolves around the following core values: • Make clients your partners It works very closely with the owners and makes them partners in managing the project. Through regular status updates, it keeps them informed about potential risks and cost savings...

...People’s Belief in Ghost Have you ever walked down a dark alley at midnight? If so, maybe you started hearing strange sounds or voices without seeing someone there. Suddenly, a dog starts barking at nothing and you felt a cold shiver down your backbone for no apparent reason. If you experienced these things, it could be a good reason to believe in ghosts. Theoretically, a ghost is the soul of a person who has died and somehow has gotten stuck between two worlds. Normally, they do not know that they are dead and they still live amongst us. A ghost can be perceived by the senses of living people, such as by sight (apparition), hearing (sound, voice) and touch. Many stories have documented that ghosts are real but many people think they are just people’s illusions. Ghost is a popular topic throughout the millennium. They have appeared in numerous works and art forms, from the play “Macbeth” by Shakespeare to the Christian Bible and even some folk ghost stories have been released. The existence of ghosts was still a big mystery of mankind over hundreds of years. Some people believe in ghosts while others do not. To convince people of the existence of ghosts, there are several stories that can be told. One of them is the United States White House’s haunted story. The White House, where the United States President lives and work, has long been considered as the worst haunted place in that country. Harry Truman, America’s 33rd president, had affirmed that...

...I HISTORY OF ITALY History The migrations of Indo-European peoples into Italy probably began about 2000 B.C. and continued until 1000 B.C. From about the 9th century B.C. until it was overthrown by the Romans in the 3rd century B.C. , the Etruscan civilization was dominant. By 264 B.C. , all Italy south of Cisalpine Gaul was under the leadership of Rome. For the next seven centuries, until the barbarian invasions destroyed the western Roman Empire in the 4th and 5th centuries A.D. , the history of Italy is largely the history of Rome. From 800 on, the Holy Roman Emperors, Roman Catholic popes, Normans, and Saracens all vied for control over various segments of the Italian peninsula. Numerous city-states, such as Venice and Genoa, whose political and commercial rivalries were intense, and many small principalities flourished in the late Middle Ages. Although Italy remained politically fragmented for centuries, it became the cultural center of the Western world from the 13th to the 16th century. Etymology The assumptions on the etymology of the name "Italia" are very numerous and the corpus of the solutions proposed by historians and linguists is very wide. According to one of the more common explanations, the term Italia, from Latin: Italia, was borrowed through Greek from the Oscan Víteliú, meaning "land of young cattle" (cf. Lat vitulus "calf", Umbvitlo "calf").The bull was a symbol of the southern Italic tribes and was often depicted goring the Roman wolf as a defiant symbol...
