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.
