World-Wide Web Server
The Web is a network within the Internet consisting of:
1) servers that provide information in hypertext
format, and 2) clients that relay user input to the
server, which displays information on the servers in
the user-specified format. While the FTP server and
Gopher server present information in a hierarchical
directory structure, Web information is presented in
pages. A page can be an index or a document. Pages
have hypertext entries, like those in Microsoft
Windows Help files, that are linked to other Web
pages. (A link can connect users to a page on any of
the thousands of WEB servers, and can also connect
users to other kinds of Internet resources.) Users
access information, or navigate through the Internet,
by selecting highlighted words (links) in the
documents, including indexes, that are shared on
WEB servers.
The commands used by the Web are defined in the
Hypertext Transfer Protocol (HTTP).
