<
World-Wide Web, networking, hypertext> (WWW, W3, The
Web) An
Internet client-server hypertext distributed information
retrieval system which originated from the
CERN High-Energy
Physics laboratories in Geneva, Switzerland.
An extensive user community has developed on the
Web since its
public introduction in 1991. In the early 1990s, the
developers at CERN spread word of the Web's capabilities to
scientific audiences worldwide. By September 1993, the share
of
Web traffic traversing the
NSFNET Internet backbone
reached 75
gigabytes per month or one percent. By July 1994
it was one
terabyte per month.
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.
NCSA
Mosaic,
Netscape Navigator, 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.
Most clients and servers also support "forms" which allow the
user to enter arbitrary text as well as selecting options from
customisable menus and on/off switches.
Following the widespread availability of
web browsers and
servers, many companies from about 1995 realised they could
use the same software and protocols on their own private
internal
TCP/IP networks giving rise to the term
"
intranet".
The
World Wide Web Consortium is the main standards body for
the
web.

The best way to access
this dictionary is via the
Web since
you will get the latest version and be able to follow
cross-references easily. If you are reading a plain text
version of this dictionary then you will see lots of curly
brackets and strings like
http://hostname/here/there/page.html.
These are transformed into hypertext links when you access it
via the
Web.
