Intranets are fundamentally "small" Internets. They employ the same network facilities which the Internet does, however access is limited to a restricted sphere. For example, a company can set up an intranet in the confines of the company itself. Access can be firmly controlled and restricted to authorized employees & staff. There is no connection to the Internet or any other outside network. Functions such as web sites, file uploads & downloads, and e-mail is accessible on intranets in the confines of the network.
