identical networks. In most twisted pair Ethernet configurations, repeaters are required
for cable runs longer than 100 metres. A repeater does not change the functionality of the
network; instead, it makes the signal strong before it degrades.

Repeaters are also extensively used in broadcasting where they are termed as translators
or boosters.

CTM: Repeater is a device that amplifies a signal that is transmitted across the network so that the signal is
received in the same way as it is sent.

9. Router: A routers is a networking device that forwards data packets from the source
machine to the destination machine by using the shortest path. Routers are used at the
network layer, which is the third layer of the OSI model.
