U
Unicode
A character-coding scheme designed to be an extension of ASCII. By using 16 bits for each
character (rather than ASCII's 7), Unicode can represent almost every character of every language
and many symbols (such as "&") in an internationally standard way, eliminating the complexity of
incompatible extended character sets and code pages. Unicode's first 128 codes correspond to
those of standard ASCII.
uniform resource locator (URL)
A draft standard for specifying an object on a network (such as a file, a newsgroup, or, with JDBC,
a database). URLs are used extensively on the World Wide Web. HTML documents use them to
specify the targets of hyperlinks.

V

W
World Wide Web (WWW)
An Internet client-server hypertext distributed information retrieval system that originated from the
CERN High-Energy Physics laboratories in Geneva, Switzerland. On the WWW everything
(documents, menus, indexes) 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 by FTP, Gopher, Telnet, or news, as well as those available by means of the
HTTP protocol used to transfer hypertext documents. The client program (known as a browser)
runs on the user's computer and provides two basic navigation operations: to follow a link or to
send a query to a server.
