Internetworking

Traditionally internetworking is thought of as connecting two or more local area networks via some sort of wide area network, although this definition is evolving to include the connection of other types of computer networks such as personal area networks.

The most notable example of internetworking in practice is the Internet, which is a network of networks running different low-level protocols, unified by an internetworking protocol, the Internet Protocol (IP). The Internet Protocol supports the transmission standards required for daily Internet activities. To access the Internet, a transmission protocol (such as TCP) must be used. This is why we commonly refer to TCP and IP together as "TCP/IP", even though netcitizens may occasionally use a simpler less precise transmission protocol (called UDP) for less precise tasks such as video streaming[?].
