Internet-like networks within an enterprise

Internet-like networks within an enterprise are commonly referred to as Intranets. An intranet is a private network that is contained within an enterprise. It is used to securely share company information and computing resources among employees. Intranets are also used to facilitate working in groups and to improve the overall internal communications efforts. They are typically built using the same technologies as the Internet, such as TCP/IP (Transmission Control Protocol/Internet Protocol) and web browsers, making them easy to use and maintain. Additionally, intranets often have connections to the public Internet, protected by firewall software to prevent unauthorized access.
