A repeater is a device that operates only in the physical layer. Any signal that travel through a network can travel up-to a fixed distance due to attenuation. 


 A repeater receives the weak signal, regenerates the signals to get the original bit pattern. The repeater then sends the strengthened signal on the network.


A repeater is used to extend the physical length of a LAN.


Example 10Base5 has maximum 500m length   it can be extended by using repeater.

A repeater is not a device that can connect two LANs of different protocols.


Repeater does not amplify the signals
