In communication networks, a node (Latin nodus, ‘knot’) is either a connection point, a redistribution point or a communication endpoint (some terminal equipment). 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.[1] A passive distribution point such as a distribution frame or patch panel is consequently not a node.
