World-Wide WebWorld-Wide Web(World-Wide Web, networking, hypertext)An extensive user community has developed on the Web since itspublic introduction in 1991. In the early 1990s, thedevelopers at CERN spread word of the Web's capabilities toscientific audiences worldwide. By September 1993, the shareof Web traffic traversing the NSFNET Internet backbonereached 75 gigabytes per month or one percent. By July 1994it was one terabyte per month. On the WWW everything (documents, menus, indices) isrepresented to the user as a hypertext object in HTMLformat. Hypertext links refer to other documents by theirURLs. These can refer to local or remote resourcesaccessible via FTP, Gopher, Telnet or news, as well asthose available via the http protocol used to transferhypertext documents. The client program (known as a browser), e.g. NCSAMosaic, Netscape Navigator, runs on the user's computerand provides two basic navigation operations: to follow alink or to send a query to a server. A variety of clientand server software is freely available. Most clients and servers also support "forms" which allow theuser to enter arbitrary text as well as selecting options fromcustomisable menus and on/off switches. Following the widespread availability of web browsers andservers, many companies from about 1995 realised they coulduse the same software and protocols on their own privateinternal TCP/IP networks giving rise to the term"intranet". The World Wide Web Consortium is the main standards body forthe web. An article by John December. A good place to start exploring. WWW servers, clients and tools.

The best way to access this dictionary is via the Web sinceyou will get the latest version and be able to followcross-references easily. If you are reading a plain textversion of this dictionary then you will see lots of curlybrackets and strings like http://hostname/here/there/page.html.
