repeater

[ri′pēd·ər]
(electricity)
(electronics)
An amplifier or other device that receives weak signals and delivers corresponding stronger signals with or without reshaping of waveforms; may be either a one-way or two-way repeater. Also known as regenerator.
An indicator that shows the same information as is shown on a master indicator. Also known as remote indicator.

repeater

(networking, communications)
A network or communications device which propagates electrical signals from one cable to another, amplifying them to restore them to full strength in the process. Repeaters are used to counter the attenuation which occurs when signals travel long distances (e.g. across an ocean).

A network repeater is less intelligent than a bridge, gateway or router since it works at the physical layer.

repeater

(1) A communications device that amplifies (analog) or regenerates (digital) the data signal in order to extend the transmission distance. Available for both electronic and optical signals, repeaters are used extensively in long distance transmission. They are also used to tie two LANs of the same type together. Repeaters work at layer 1 of the OSI model. See bridge and router.

(2) The term may also refer to a multiport repeater, which is a hub in a 10Base-T network.
