Glossary of Terms

HTTP
Short for HyperText Transfer Protocol, the underlying protocol used by the World Wide Web. HTTP
defines how messages a
re formatted and transmitted, and what actions Web servers and browsers
should take in
response to various commands. For example, when you enter a URL in your browser,
this actually se
nds an HTTP command to the Web server directing it to fetch and transmit the
requested Web page.
HTTP is called a stateless protocol because each command is executed independently, without any
knowledg
e of the commands that came before it. This is the main reason that it is difficult to
implemen
t Web sites that react intelligently to user input. This shortcoming of HTTP is being
addressed in a number of new technologies, including ActiveX, Java, JavaScript and cookies.

The IEEE (
Institute of Electrical and Electronic Engineers) standard that defines the CSMA/CD

and 10BASE-T Ethernet
