Abstract

R — Repeater. A device that operates at the physical layer of communications, used to regenerate and amplify signals in order to extend transmission distance. It is important to note that a repeater only overcomes the electrical restrictions of the media used, but cannot be used to increase the time limitations related to the topology used. It also links multiple segments of an Ethernet network in either a bus or star topology. Fully 802.3-compliant repeaters regenerate and retime the signal of each packet of information and automatically partition and isolate faulty segments when collisions occur on the network. A special kind of repeater is a hub, a wiring concentrator repeater that brings together the connections from multiple network nodes in a star topology. Unlike bridges (see B), routers (see next R) and gateways, which connect different networks at different layers, repeaters operate on the same network.
