It is an electronic device which receives signals and transmit it.
Repeaters are used to extend the transmission so that the signal can cover long distances or be received on the other side of destruction.
Ex – If we want to send an information from device 1 to device 3, repeater is required.
How it works?
The information which needs to be send first go to device 2 but this device doesn’t keep that information but further with the help of repeater it forwards the information.
