Role of repeater

The RP repeater, which works on the physical layer of the OSI, is the center of all the nodes on the LAN, and its function is to amplify the signal, compensate the attenuation of the signal, and support the long distance communication. Repeater. Working in the physical layer is only a function of extending the transmission distance, and is transparent to high level protocols. In fact, the network connected by repeater is equivalent to a larger network composed of the same wire. Repeaters can also connect different transmission media (10Base 5 and 10Base 2) to the same LAN interconnection above the data link layer.
