the Three Protocols - Why The Web Works, How It All Happened

The World Wide Web is one of several utilities—including e-mail, File Transfer Protocol (FTP), Internet Relay Chat (IRC), Telnet, and Usenet—that form the Internet. At the heart of the Web is a system of many Web servers. While the term server is normally used to describe the computers that host Web sites, it also can refer to the software used to store Web pages. The World Wide Web Consortium (W3C) describes the Web as "the universe of network-accessible information, the embodiment of human knowledge." This statement describes the vision of the Web's creator, a computer scientist named Tim Berners-Lee, who developed three critical protocols that make it work.
