Just as one can distinguish between "an internet" and "the
Internet", one can refer to "a web" as a collection of sites
providing information by the means described here (perhaps on an
intranet), and "the Web", which is the single, large,
interconnected web available on nearly all public Internet
sites. The Web grew out of a project at CERN, beginning around
1989, where Tim Berners-Lee and Robert Cailliau[?] built the
prototype system that became the core of what is now the World
Wide Web. The original intent of the system was to make it
easier to share research papers among colleagues. The original
name of the first prototype was Enquire Within Upon Everything.
The core functionality of the Web is based on three standards:
The Uniform Resource Locator (URL), which specifies how each
page of information is given a unique "address" at which it can
be found; Hyper Text Transfer Protocol (HTTP), which specifies
how the browser and server send the information to each other,
and Hyper Text Markup Language (HTML),
