HISTORY OF INTERNET

THE BEGINNING OF THE INTERNET It will help in discussing the beginnings of the Internet to define what the Internet is. Now, you can get as many different definitions of what the Internet is as dictionaries you have. But for most of us, the simple description, a "worldwide system of interconnected networks and computers" is pretty good and adequate. But when people get more technical, they tend to add to the definition terms such as "a network that uses the Transmission Control Protocol - Internet protocol" (or TCP/IP). Many people have heard that the Internet began with some military computers in the Pentagon called Arpanet in The theory goes on to suggest that the network was designed to survive a nuclear attack. However, whichever definition of what the Internet is we use, neither the Pentagon nor 1969 hold up as the time and place the Internet was invented. A project which began in the Pentagon that year, called Arpanet, gave birth to the Internet protocols sometime later (during the 1970's), but 1969 was not the Internet's beginnings. Surviving a nuclear attack was not Arpanet's motivation, nor was building a global communications network.

Bob Taylor, the Pentagon official who was in charge of the Pentagon's Advanced Research Projects Agency Network (or Arpanet) program, insists that the purpose was not military, but scientific. The nuclear attack theory was never part of the design. Nor was an Internet in the sense we know it part of the Pentagon's 1969 thinking. Larry Roberts, who was employed by Bob Taylor to build the Arpanet network, states that Arpanet was never intended to link people or be a communications and information facility. Arpanet was about time-sharing. Time sharing tried to make it possible for research institutions to use the processing power of other institutions computers when they had large calculations to do that required more power, or when someone else's facility might do the job better. What Arpanet did in 1969 that was important was to develop a variation of a technique called packet switching. In 1965, before Arpanet came into existence, an Englishman called Donald Davies had proposed a similar facility to Arpanet in the United Kingdom, the NPL Data Communications Network. It never got funded; but Donald Davies did develop the concept of packet switching, a means by which messages can travel from point to point across a network. Although others in the USA were working on packet switching techniques at the same time (notably Leonard Kleinrock and Paul Baran), it was the UK version that Arpanet first adopted.

IMPORTANT INTERNET PEOPLE

Bill Gates Entrepreneur Bill Gates founded the world's largest software business, Microsoft, with Paul Allen, and subsequently became one of the richest men in the world. Bill Gates was born William Henry Gates III on October 28, 1955, in Seattle, Washington. Gates began to show an interest in computer programming at the age of 13 at the Lakeside School. He pursued his passion through college. Striking out on his own with his friend and business partner Paul Allen, Gates found himself at the right place at the right time. Through technological innovation, keen business strategy and aggressive business tactics, he built the world's largest software business, Microsoft. In the process, Gates became one of the richest men in the world.

Tim Berners-Lee Tim Berners Lee is a British computer scientist who is credited with inventing the World Wide Web (WWW). Berners-Lee enabled a system to be able to view web pages (hypertext documents) through the internet. He also serves as a director fo the World Wide Web Consortium (W3C) which overseas standards for the internet and world wide web. Berners-Lee has also been concerned about issues relating to freedom of information and censorship on the internet.

Leonard Kleinrock ºDr. Leonard Kleinrock pioneered the mathematical theory of packet networks, the technology underpinning the Internet. For his enormous contribution to understanding the power of packet networks he was honored with the Charles Stark Draper Award as one of the fathers of the Internet, along with Vinton Cerf, Robert Kahn, and Larry Roberts. He is a developer of ARPANET, the seedling that grew into today’s global Internet, and his laboratory’s UCLA Host computer became the first ARPANET node in September A month later, he directed the first transmission to pass over the blossoming network.

How do we use internet?

We use internet every day for do diferent things´,for example: ∞ Look for information for do our homework. ∞ Chat with friends and family. ∞ Download photos and music. ∞ Post comments and images in many webpages. ∞ Play games online with other people.
