ISDN VS. Cable Modem
1.0 Introduction
The Internet is a network of networks that interconnects computers around the world, supporting both business and residential users. In 1994, a multimedia Internet application known as the World Wide Web became popular. The higher bandwidth needs of this application have highlighted the limited Internet access speeds available to residential users. Even at 28.8 Kilobits per second (Kbps)—the fastest residential access commonly available at the time of this writing—the transfer of graphical images can be frustratingly slow.
This report examines two enhancements to existing residential communications infrastructure: Integrated Services Digital Network (ISDN), and cable television networks upgraded to pass bi-directional digital traffic (Cable Modems). It analyzes the potential of each enhancement to deliver Internet access to residential users. It validates the hypothesis that upgraded cable networks can deliver residential Internet access more cost-effectively, while offering a broader range of services.
The research for this report consisted of case studies of two commercial deployments of residential Internet access, each introduced in the spring of 1994:
· Continental Cablevision and Performance Systems International (PSI) jointly developed PSICable, an Internet access service deployed over upgraded cable plant in Cambridge, Massachusetts;
· Internex, Inc. began selling Internet access over ISDN telephone circuits available from Pacific Bell. Internex's customers are residences and small businesses in the "Silicon Valley" area south of San Francisco, California.
2.0 The Internet
When a home is connected to the Internet, residential communications infrastructure serves as the "last mile" of the connection between the home computer and the rest of the computers on the Internet. This section describes the Internet technology involved in that connection.
This section does not discuss other aspects of Internet technology in detail; that is well done elsewhere. Rather, it focuses on the services that need to be provided for home computer users to connect to the Internet.
2.1
ISDN and upgraded cable networks will each provide different functionality (e.g. type and speed of access) and cost profiles for Internet connections. It might seem simple enough to figure out which option can provide the needed level of service for the least cost, and declare that option "better." A key problem with this approach is that it is difficult to define exactly the needed level of service for an Internet connection. The requirements depend on the applications being run over the connection, but these applications are constantly changing. As a result, so are the costs of meeting the applications' requirements.
The most predominant attribute of a graffiti artist is their mindset, for a graffitist is constantly surveying the streets in search for a new spot to “bomb” as well as examining the work of fellow writers. For instance, when a graffiti artist looks at an empty wall or a distant water tower they envision a canvas suitable for displaying their graffiti. A graffiti artist uses specific terminology when speaking to fellow writers as well as average people interested in this illegal art form. The use of terms, such as “tag,” “throw-up,” and “burner” are used to describe different styles of graffiti letters. In addition, the term “bomb” is used when a graffitist paints on numerous surfaces in a given area. When analyzing the desires of a graffitist, they explain the desire to go “all-city.” The term “all-city” describes a writers’ aspiration to display his graffiti throughout the entire city. The lifestyle of a graffiti artist tends to be more active than that of an average person, for graffitist go “bombing” during late hours of the night. The reason for these late-night paint excursions is to avoid cont...
Charles Dickens writes this book explaining the French Revolution, in which the social and economic systems in France had huge changes and the French monarchy collapsed. This causes high taxes, unfair laws, and the poor being mistreated. Charles Dickens shows that cruelty of other people will lead to a revolution and in addition to the revolution more cruelty will occur. He explores the idea of justice and violence through the use of ambiguous characters with positive and negative qualities, meaning that they have to different sides to them; for example, Charles Darnay, Sydney Carton, and Dr. Manette. Throughout the story of A Tale of Two Cities, Charles dickens uses ambiguous characters to shows how violence and cruelty can be stopped through the power of true sacrifice.

These women have each incorporated their personal perspective on how women are viewed in society, voice and position wise. Each writer reveals the shortcomings in the core of society, especially “The Yellow Wallpaper” by Charlotte Perkins Gilman, “The Story of an Hour” by Kate Chopin, and “Roman Fever” by Edith Wharton these stories put forth a large quantity of aspects that specific the restriction and containment with which women were encountered with. Chopin, Gilman, and Wharton effectively pointed out the problems that women still encounter, and explain how they were all connected identical around the idea of social complexity and male superiority.
The identity of a graffiti artist is hardly ever known unless they want to tag their art with their name or a nickname. Graffiti writers as a subculture are trying to express their political views through civil disobedience by painting pictures that speak out against the government. This subculture developed because they were tired of being oppressed by the government. Graffiti is one of the most enduring acts of protest. It is an important tool for the resistance movement as a way to publicize their protest. It is a visible and powerful form of protest that is going to promote change in the social justice by allowing oppressed groups of people express their viewpoints without being penalized by the
It is clear that throughout the Western tradition men and women occupied different roles in different civilizations. Separate rights and privileges were awarded to either sex based upon the places that their cultures designated for them. Though every culture had those that would (often justifiably) upset the order of things by challenging conventional gender roles, ultimately, one was more likely to be confined by the limitations of what society said one could do. Religion in particular tended to codify the separate treatment of men and women; it could not be easily defied, because of the divine power behind it. Although no two religions were quite the same, a few generalizations can be made; monotheistic cultures allowed less fluidity between masculine and feminine gender roles and gave males a more powerful place in their societies, where polytheistic gender roles permitted greater flexibility and were more likely to sanction female authority figures.
Paul was accepted back into his Special Education class and was also allowed to do small jobs at the business he had stolen from. Paul agreed not to skip school for the theater and his father also agreed that if Paul was able to maintain passing grades that his father would take him to the theater.
Charles Dickens’s voice varies from being sympathetic with the revolutionaries, to a feeling of discord with their method of revolting. A Tale of Two Cities revolves around the French revolution and the tension in England. Dickens gives the tale of a family caught in the conflict between the French aristocracy and radicals. In the course of the book, the family handles extreme difficulty and obscurity. Dickens’s neutrality, though sometimes wavering from side to side, is apparent throughout each book in the novel.
People around the world have different ways to express their feelings through. It could be done legally or illegaly. One way in which it could be done is through art like graffiti. Graffiti is a form of art where people express their feelings by spraying colors on street walls. It is actually a very interesting kind of art, as it is not easy to draw with sprays and to express yourself using some kind of symbols on walls that represent something deep inside you. Since the beginning of time, people have been debating on whether graffiti is legal or not. If you think about it for a second, you will find each and every reason for graffiti to be legal, but people till now tend to accuse it as a form of crime. Since when is art a crime? Since when is expressing your feelings in a peaceful way is a crime? Graffiti could not just be used on walls of other people’s property, it as well could be done on portraits and sold and actually in Brazil many people travel there to see the graffiti portraits in the galleries. Graffiti grabs people attention in a way and raises people’s awareness of something through drawing. Isn’t it just beautiful to draw something that grabs people attention and raises their awareness towards something and then credit you for doing so? Therefore, graffiti is passionate beautiful kind of art that I do not think it should be seen as a crime, instead as an astonishing form of art.
Graffiti is a form of art that people use to express themselves and to convey various messages to people in a particular community. In the movie "Graffiti Verite':. One of the graffiti artist explained that his purpose in doing graffiti is that it allows him to "express his anger' on the wall. Another kid by the name of "Jipsie" said that graffiti is a "form of growth". There were several different explanations that artists shared as well as several different reasons why they like graffiti. The common theme among the graffiti artist and taggers was that graffiti is simply a form of self-expression (Bryan). At the end of the film one tagger made a comment and said, "graffiti is not vandalism, but it is a beautiful crime". This comment did not make sense to me. Committing a crime, a hideous act, is not a beautiful thing to do by any means. Graffiti does not mean people can go around and draw and spray paint on other peoples property. Regardless of what types of graffiti are being expressed by the tagger, this type of self expression is considered vandalism when people decide to draw, destroy, or violate any persons property without consent. As a result of taggers committing the crime of vandalism, property owners, concerned citizens, and law enforcement officers spend too much time, money, and energy trying to put an end to the unlawful act of vandalism.
"The storming of the Bastille…the death carts with their doomed human cargo…the swift drop of the guillotine blade-this is the French revolution that Charles Dickens vividly captures in his famous work "A Tale of two cities". With dramatic eloquence, he brings to life a time of terror and treason, a starving people rising in frenzy and the to overthrow a corrupt and decadent regime. With insight and compassion, he casts his novel of unforgettable scenes with unforgettable characters: the sinister Madame defarge, knitting her patterns of death, the gentle lucie manette, unswerving in her devotion to her broken father: the heroic Sydney Carton, who gives his life for the love of a girl who will never be his."
At the beginning of A Tale of Two Cities (1859), Dickens once again expresses his concern. The novel opens in 1775, with a comparison of England and pre-revolutionary France. While drawing parallels between the two countries, Dickens also alludes to his own time: "the period was so far like the present period, that some of its noisiest authorities insisted on its being received, for good or for evil, in the superlative degree of comparison only" (1; bk. 1, ch. 1). The rest of the chapter shows that Dickens regarded the condition to be an 'evil' one, since he depicts both countries as rife with poverty, injustice, and violence due to the irresponsibility of the ruling elite (1-3; bk. 1, ch. 1). As the novel unfolds, however, England becomes a safe haven for those escaping the violence perpetrated by the French Revolution. In this paper, I shall argue that A Tale of Two Cities reflects the popular confidence in the stability of England in the eighteen-fifties, despite Dickens's suggestions at the beginning. A Tale of Two Cities thus becomes a novel about the England and the English of Dickens's time. And yet, many people today would believe that the novel is essentially about the French Revolution, which brings me to my second point. If in the nineteenth century the novel served to affirm the stability of Britain, in this century it has been greatly influential in the formation of the popular image of the French Revolution, mainly thanks to film and television adaptations. The purpose of this paper is to look at the popular reception of the novel from the time of its first publication in 1859 to the nineteen-nineties.
Mention the word graffiti and what typically comes to mind is something unpleasant and distasteful like indecent language scribbled on a wall of a store or crude pictures. Most graffiti is characterized as vandalism on property that does not belong to the culprit. Graffiti also displays negative graphics that promote some type of vulgar message such as violence, sex, drugs, gangs, and racism. On the other hand, when the terms “street” and “art” come together, a blast of colorful creations upon blank slates on the street comes to mind. Although street art is technically considered graffiti, it is a type of graffiti with positive qualities, but certain figures in society find street art to be, in some way, disruptive. If used properly, street art can be appreciated artistically and socially. Despite the negative stigma attached to graffiti, street art has emerged as a progressive valuable art form whose vast history, surge in popularity, and urge for social change warrant its classification as a fine art.
In our society, there has been a revolution which competes that of the industrial revolution. It is called technological revolution. At the top of the technological revolution is what we call, the Internet. In the following report we will be discussing about what the internet is about in general and how it might be in the future, why it is necessary in our everyday lives, and why has it become so important to everyone (i.e. companies, individuals ).
The Internet has revolutionized the computer and communications world like nothing before. The Internet enables communication and transmission of data between computers at different locations. The Internet is a computer application that connects tens of thousands of interconnected computer networks that include 1.7 million host computers around the world. The basis of connecting all these computers together is by the use of ordinary telephone wires. Users are then directly joined to other computer users at there own will for a small connection fee per month. The connection conveniently includes unlimited access to over a million web sites twenty-four hours a day, seven days a week. There are many reasons why the Internet is important these reasons include: The net adapts to damage and error, data travels at 2/3 the speed of light on copper and fiber, the internet provides the same functionality to everyone, the net is the fastest growing technology ever, the net promotes freedom of speech, the net is digital, and can correct errors. Connecting to the Internet cost the taxpayer little or nothing, since each node was independent, and had to handle its own financing and its own technical requirements.
