Link
A link is a collection of one or more segments connected together by
repeaters.
Each node in a link
must have a unique address, ranging from 1…99, to
function on the network.
Bridge
A bridge is a device that acts as a communication connection between
networks. Multiport bridges selectively forward packets of network
information from one linked segment to another segment. I/O cannot be
controlled across a bridge, only unscheduled messaging is possible.
