Node (networking)

In telecommunications networks, a node (Latin: nodus, ‘knot’) is either a redistribution point or a communication endpoint.

Equipment, such as an Ethernet hub or modem with serial interface, that operates only below the data link layer does not require a network address.

In cable television systems (CATV), this term has assumed a broader context and is generally associated with a 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.
