Show answer & explanation
Correct answer: A
The Automatic Repeat reQuest (ARQ) is used to ensure correct data delivery over unreliable communication channels.
It detects lost or corrupted packets
It requests retransmission of incorrect packets
It uses acknowledgements (ACK/NACK)
Because of this, ARQ ensures reliable data transfer between sender and receiver.
