Intranet

An intranet is an access restricted network used internally in an
organisation. Typically the term refers to the internal web site. The same
concepts and technologies of the world wide web such as web browsers and
servers running on the internet protocol suite are used to build an
intranet. Other internet protocols are commonly used as well, especially ftp
and email. There is often an attempt to use internet technologies to provide
new interfaces with corporate 'legacy' data and information systems.
