it is tempting to compare a repeater to an amplifier, but the comparision is inaccurate. according to Forouzan, an amplifier cannot discriminate between the intended signal and noise; it amplifies equally everything fed into it. a repeater does not amplify the signal; it regenerates the signal. when it receives a weakened or corrupted signal, it creates a copy, bit for bit, at the original strength.
a repeater is a regenerator; not an amplifier
a repeater forwards every bit; it has no filtering capability
a repeater connects segments of a LAN
Difference between Amplifier and Repeater 1. Amplifier is used to magnify a signal, whereas repeater is used to receive and retransmit a signal with a power gain. 2. Repeater has an amplifier as a part of it. 3. Sometimes, amplifiers introduce some noise to the signal, whereas repeaters contain noise eliminating parts.
A repeater that does not distinguish between noise and signal; it amplifies both.
A signal repeater is designed to extend the input signal for longer lengths than the original cable design. It encorporates an amplifier to boost the signal.
Amplifier repeater
A bridge acts as "bridge" between two networks or network subnets. A repeater merely strengthens the signal. You can have a repeater that only acts on one wire.
A hub is a multi-port repeater. Therefore, the difference is that a repeater has only 2 ports and a hub has more than two ports. Other than that, they operate identically.
A transistor can act as an amplifier. An amplifier you use for music might have many transistors as well as many other types of components. Transistors have other applications as well.
