JDBC Type 4 Driver 1.1 Programmer's Reference

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.
URL

V
virtual machine (VM)
A self-contained operating environment that behaves as if it is a separate computer. See
also Java virtual machine and Java Hotspot virtual machine.
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.
