Several types of devices are used in LANs, MANs, and WANs to provide intercommunication between computers and networks. The use of these devices varies according to their functionality, capabilities, intelligence, and network placement. We will look at the following devices:
A repeater provides the simplest type of connectivity, because it only repeats and amplifies electrical signals between cable segments, which enables it to extend a network.
Repeaters work at the physical layer and are add-on devices for extending a network connection over a greater distance. The device amplifies signals because signals attenuate the farther they have to travel.
Repeaters can also work as line ...
