The History of the Internet
The Internet has update the computer and communications world like nothing before. The invention of the telegraph, telephone, radio, and computer set the stage for this unprecedented integration of capabilities. The Internet is at once a world-wide broadcasting capability, a mechanism for information distribution, and a medium for collaboration and interaction between individuals and their computers without regard for geographic location.
The Internet represents one of the most successful examples of the benefits of sustained investment and commitment to research and development of information infrastructure. Beginning with the early research in packet switching, the government, industry and academia have been partners in evolving and deploying this exciting new technology. Over its fifteen year history, the Internet has functioned as a collaboration among cooperating parties. Certain key functions have been critical for its operation, not the least of which is the specification of the protocols by which the components of the system operate.
To get to the origins of the Internet, we have to go back in time to 1957. You probably have no cause to remember, but it was International Geophysical Year, a year dedicated to gathering information about the upper atmosphere during a period of intense solar activity. Eisenhower announced in 1955 that, as part of the activities, the USA hoped to launch a small Earth orbiting satellite. Then Kremlin announced that it hoped to do likewise. Planning in America was focussed on a sophisticated three stage rocket, but in Russia they took a more direct approach, on 4 October 1957 the USSR launched (a 70 kgs bleeping sphere the size of a medicine ball) into Earth orbit. The effect in the United States was electrifying, since it seemed overnight to wipe out the feeling on invulnerability the country had enjoyed since the explosion of the first nuclear bomb thirteen years before. One of the immediate reactions was the creation of the Advanced Research Projects Agency within the Ministry of Defense. Its mission was to apply state-of-the-art technology to US defense and to avoid being surprised (again!) by technological advances of the enemy. It was also given interim control of the US satellite program until the creation of NASA in October 1958.
ARPA became the technological think-tank of the American defense effort, employing directly a couple of hundred top scientists and with a budget sufficient for sub-contracting research to other top American institutions. Although the advanced computing would come to dominate its work, the initial focus of ARPA\'s activities were on space, ballistic missiles and nuclear test monitoring. Even so, from the start ARPA was interested in communicating between its operational base and its sub-contractors, preferably through direct links between its various computers. In October 1972 ARPANET went \'public\'. At the First International Conference on Computers and Communication, held in Washington DC, ARPA scientists demonstrated the system in operation, linking computers together from 40 different locations. This stimulated further research in scientific community throughout the Western World. Soon other networks would appear.
Here we have the first true computer network. Since it is all still fairly basic, it is worth considering the underlying principles have basically remained the same (even if they, mercifully, operate far faster and look much prettier). We start off with a passive terminal and an active host, a keyboard and a computer. They are linked together by a cable. By typing in commands recognized by a computer, you can use the programs stored in its computer, access its files (and modify them and print them out as desired). Most people can envisage this arrangement within a single building, or complex of buildings.
The original ARPANET grew into the Internet. The Internet was based on the idea that there would be multiple independent networks of rather arbitrary design, beginning with the ARPANET as the pioneering packet switching network, but soon to include packet satellite networks, ground-based packet radio networks and other networks. The Internet as we now know it embodies a key underlying technical idea, namely that of open architecture networking. In this approach, the choice of any individual network technology was not dictated by a particular network architecture but rather could be selected freely by a provider and made to interwork with the other networks through a meta-level "Internetworking Architecture".

INTRODUCTION In the future, existing fixed networks will be complemented by mobile networks with similar numbers of users. These mobile users will have identical requirements and expectations to the fixed users, for on-demand applications of telecommunications requiring high bit-rate channels.

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
Macintosh vs. IBMMacintosh vs. IBM The IBM and Macintosh computers have been in competition with each other for years, and each of them have their strong points. They both had their own ideas about where they should go in the personal computer market. They also had many developments, which propelled themselves over the other. It all started when Thomas John Watson became president of Computing Tabulating Recording in 1914, and in 1924 he renamed it to International Business Machines Corporation. He eventually wi

Neural NetworksNeural Networks A neural network also known as an artificial neural network provides a unique computing architecture whose potential has only begun to be tapped. They are used to address problems that are intractable or cumbersome with traditional methods. These new computing architectures are radically different from the computers that are widely used today. ANN\'s are massively parallel systems that rely on dense arrangements of interconnections and surprisingly simple processors (Cr95, Ga93).
TelecommunicationTelecommunication 1. Introduction Computer and telephone networks inflict a gigantic impact on today\'s society. From letting you call John in Calgary to letting you make a withdraw at your friendly ATM machine they control the flow of information. But today\'s complicated and expensive networks did not start out big and complicated but rather as a wire and two terminals back in 1844. From these simple networks to the communication giants of today we will look at the evolution of the network and

The system would combine the technologies used to create the machines that put the car together, with the people that run the machines, the assembly line process for building the car, and the salesman that sells the car, which creates the original mechanism for the cars to be built. 2) Hierarchies require a vertical chain of command
MultimediaMultimedia Multimedia, or mixed-media, systems offer presentations that integrate effects existing in a variety of formats, including text, graphics, animation, audio, and video. Such presentations first became commercially available in very primitive form in the early 1980s, as a result of advances that have been made in digital compression technology-- particularly the difficult area of image compression.

AztecsAztecs According to their own history, the Aztecs, who called themselves the Tenochca or Mexica, started as a small nomadic tribe originating from a place called Aztlan. Aztlan existed somewhere in the southern part of California or the north west of Mexico. At this time they were Nahuatl speaking. During the twelfth century they started a period of wandering and in the thirteenth century they came across Mexico\'s central valley. There they decided to settle. The reason for this is a prophecy.

FREDRIC JAMESON AND THE LIMITS OF POSTMODERN THEORFREDRIC JAMESON AND THE LIMITS OF POSTMODERN THEORY by Sean Homer The impetus behind this paper has been the recent publication of Fredric Jameson\'s 1991 Welleck Lectures, The Seeds of Time.1 As these lectures were delivered a decade after Jameson\'s initial attempts to map the terrain of postmodernity it appeared to me to provide an occasion to reflect upon the current status of Jameson\'s highly influential and much criticised theory of postmodernism as the cultural logic of late capitalism.
