Full Answer

There are two main forms that an intranet can take. A local-area network, or LAN, is built in a single location and requires a direct physical connection to access the network. A wide-area network, or WAN, can be accessed through a direct physical connection or a remote connection. Some WANs allow password-protected remote access via a standard Internet connection, while others require members to connect to a dedicated communication line separate from the larger Internet.

Apart from accessibility, the Internet and intranets are very similar. They are both constructed from the same types of hardware components, including routers, servers and data network cables. What’s more, the two types of networks are based on the same network- and data-sharing protocols, including the Transmission Control Protocol and the Internet Protocol. These protocols, commonly known as TCP/IP, make up the basic foundation of all modern computer network communications.
