A repeater is an electronic device in a communication channel that increases the power of a signal and retransmits it, allowing it to travel further. Since it amplifies the signal, it requires a source of electric power.
We'll start with the simplest device, the Hub. A hub is a repeater, which is a OSI model device, the simplest possible. A hub takes the data that comes into a port and sends it out all the other ports in the hub. It doesn't perform any filtering or redirection of data.
