Editing Node (networking) (section)

== Telecommunications ==
In the fixed telephone network, a node may be a public or private [[telephone exchange]], a [[remote concentrator]] or a computer providing some [[intelligent network service]]. In cellular communication, switching points and databases such as the [[base station controller]], [[home location register]], [[gateway GPRS Support Node]] (GGSN) and [[serving GPRS support node]] (SGSN) are examples of nodes. Cellular network [[base station]]s are not considered to be nodes in this context.

In [[cable television]] systems (CATV), this term has assumed a broader context and is generally associated with a [[Fiber-optic communication|fiber optic]] node. This can be defined as those homes or businesses within a specific geographic area that are served from a common fiber optic [[Receiver (information theory)|receiver]]. A fiber optic node is generally described in terms of the number of "homes passed" that are served by that specific fiber node.
