Question 9

Assertion. A repeater is not like an amplifier.

Reason. A repeater regenerates a signal thereby removing noise.

  1. Both A and R are true and R is the correct explanation of A.
  2. Both A and R are true but R is not the correct explanation of A.
  3. A is true but R is false.
  4. A is false but R is true.
Answer

Both Assertion and Reason are true and Reason is the correct explanation of Assertion.

Explanation
A repeater is not like an amplifier because a repeater not only amplifies the signal but also performs signal regeneration. When a signal weakens over long distances, the repeater collects the inbound packet and then retransmits it as if it were originating from the source station. This process effectively removes noise.
