network segment definition networking
A part of an Ethernet
or other network, on which all message traffic is common to all nodes, i.e. it is broadcast from one node on the segment and received by all others. This is normally because the segment is a single continuous conductor, though it may include repeaters
Since all nodes share the physical medium, collision detection
or some other protocol
is required to determine whether a message was transmitted without interference from other nodes. The receiving node inspects the destination address of a packet
to tell if it was (one of) the intended recipient(s).
Communication between nodes on different segments is via one or more routers
