Intranets are mainly "small" Internets. They use same network facilities that Internet does, though access is restricted to a limited sphere. For example, a company can set up an intranet within confines of the company itself. Access can be tightly controlled and limited to authorized staff and employees. There is no connection to Internet or any other outside network. Functions such as web sites, downloads and file uploads and e-mail is available on intranets within confines of network. Because frivolous sites are no longer available, there is no employee time lost because of accessing them. There is, of course, limitation of the networking area. Very benefit of restricting access to all of facilities available on Internet also restricts communication to other desirable locations. This is where extranet steps in. An extranet is network which connects a number of intranets in a truly mini-Internet Access is extended to all intranets connected through extranet, though, again, not to Internet. Extranets requires a constant Internet connection as well as a hypertext transfer protocol (http) server.
