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.

Extranets requires a constant Internet connection as well as a hypertext transfer protocol (http) server.
