Where did Internet come from?

The idea of the Internet is credited to Sir Tim Berners-Lee. http://en.wikipedia.org/wiki/Tim_Berners-Lee The first Web site built was at CERN and was first put online on 6 August 1991. It provided an explanation about what the World Wide Web was, how one could own a browser and how to set up a Web server. It was also the world's first Web directory, since Berners-Lee maintained a list of other Web sites apart from his own. Since he first proposed the idea some time between June and December 1980, it could be said that the World Wide Web took 11 years to develop. Although the words 'Internet' and 'World Wide Web' are often used interchangeably, they are different things. The Internet is the mechanism by which many computers all over the world are connected; the World Wide Web is a very large set of interlinked hypertext documents accessed via the Internet and depends on a protocol (called HyperText Transfer Protocol - HTTP) for linking those documents. There are other protocols used on the Internet, one of the commonest being File Transfer Protocol - FTP.
