Note: Many topics at this site are reduced versions of the text in "The Encyclopedia of Networking and Telecommunications." Search results will not be as extensive as a search of the book's CD-ROM.

A node is a network-connected device such as a workstation, a server, or a printer. Network connection devices such as bridges and routers are not usually referred to as nodes on a network, even though they have network addresses.

In the IP addressing scheme, network nodes such as computers are called "hosts," while routers are sometimes called "gateways," an older term that is rarely used today because gateways refer to application layer devices that join systems or networks and provide translation services between them.
