An Intranet is a privately maintained, secure computer network based on the communication standards of the Internet. It is a smaller version of the Internet that only the internal members of an organization can see. At the same time it is available remotely over the Internet allowing access from any physical location. Organizations can create, within their walls, a manageable, secure version of the World Wide Web. These internal Webs are growing from an explosion in the use and understanding of Internet technology.
