Repeaters

A repeater is an electronic device that operates on the physical layer of the OSI model. An amplifier cannot differentiate between the original signal and a noise signal. Repeaters do not amplify the signal; they regenerate it. When a repeater receives a signal affected by noise, it creates a copy, bit by bit, restoring it to its original strength.

Advantages of Repeaters

  • Extend the physical distance of a network.
  • Do not seriously affect network performance.

Disadvantages of Repeaters

  • Cannot
