Node (Networking)
In communication networks, a node (Latin nodus, ‘knot’) is a connection point, either a redistribution point or a communication endpoint. The definition of a node depends on the network and protocol layer referred to. A physical network node is an active electronic device that is attached to a network, and is capable of sending, receiving, or forwarding information over a communications channel. A passive distribution point such as a distribution frame or patch panel is consequently not a node.
