World Wide Web (WWW, W3, Web)

World Wide Web (WWW, W3, Web) is An Internet client-server hypertext distributed information retrieval system which originated
from the CERN High-Energy Physics laboratories in Geneva, Switzerland. On the WWW
everything (documents, menus, indices) is represented to the user as a hypertext object in
HTML format. Hypertext links refer to other documents by their URLs. These can refer to local
or remote resources accessible via FTP, Gopher, Telnet or news, as well as those available via
the HTTP protocol used to transfer hypertext documents. The client program (known as a
browser), e.g. Mosaic, Netscape, runs on the user's computer and provides two basic
navigation operations: to follow a link or to send a query to a server. A variety of client and
server software is freely available. [foldoc]
