    What is the purpose of a repeater?

    • It connects two hosts together to form a small network

    • It extends network transmission distance by boosting the signal strength

    • It connects dissimilar networks and translates between different protocols

    • It reduces the size of a network by separating a network into two smaller network segments

    Correct Answer
    A. It extends network transmission distance by boosting the signal strength
    Explanation
    A repeater simply regenerates the signal it receives on one port, boosting the signal and sending it out on another port as if it were the original physical source of the transmission. In this way it increases the signal strength, allowing it to travel further.
