FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A repeater is an active device designed to regenerate and rebroadcast an electric signal, usually to overcome the inevitable power (signal strength) losses incurred as that signal propagates along a cable.

Detailed explanation-2: -Repeaters are devices in computer networks that operate at the physical layer of the OSI model, amplifying or regenerating an incoming signal before retransmitting it.

Detailed explanation-3: -There are two types of network hubs: active and passive. A third designation, intelligent hubs, is synonymous with a switch. Active hubs repeat and strengthen incoming transmissions. They are also sometimes referred to as repeaters.

Detailed explanation-4: -The hubs that contain repeating capabilities to strengthen the signals in a network are called active hubs. The limitation of active hubs is that they magnify noise along with the signals. They are a little brighter than passive hubs because they boost the signals before passing them between nodes to the node.
