History Of Internet

The Internet was originally developed by DARPA -the Defense Advanced Research Projects Agency -as a means to share information on defenseresearch between involved universities and defenseresearch facilities.

Originally it was just email and FTP sites as well as

the Usenet, where scientists could question andanswer each other. It was called ARPANET (Advanced Research

Projects Agency NETwork). The concept was developed starting in 1964, and

the first messages passed were between UCLA and

the Stanford Research Institute in 1969. Leonard Kleinrock of MIT had published the first

paper on packet switching theory in 1961. Once the concept was proven, the organizations

involved started to lay out some ground rules forstandardization.

One of the most important was the communicationsprotocol, TCP/IP, developed by Vint Cerf and Robert Kahn in1974.

Robert Metcalfe is credited with Ethernet, which is thebasic communication standard in networked computers.

Al Gore really did have a substantial part in the US legalframework and governmental issues related to the Internet;he never said he invented it.

There wasn't just ONE person who invented the Internet.The Internet is just a way to view files and information thatsomeone puts onto a server. The Internet is just a way toaccess the information.

Leonard Kleinrock was the first person to write a paper onthe idea of packet switching (which is essential for theInternet to work. He wrote this idea in 1961.

Tim Berners-Lee, who perhaps specified technologicalapplicability and/or linguistic construction of HTML whileworking at CERN, is chiefly credited for the ease of use andwide public adoption of the web.
