Which piece of networking equipment would you use to amplify a signal so that you could use a longer segment of cable without degradation or attenuation of the signal?
A switch
A hub
A repeater
A concentrator
The correct answer is a repeater. Repeaters are used to amplify a signal so that you could use a longer segment of cable without degradation or attenuation of the signal. A hub is used to connect multiple LAN Devices. A concentrator is an alternate name for a hub. A switch is similar to a hub with the difference being switches only send packets to destination devices not all devices in the network.
