Automatic Repeat reQuest (ARQ) is an error control protocol used in data transmission systems to ensure reliable communication by automatically requesting the retransmission of data packets that are detected as erroneous or lost. It enhances data integrity and reliability by utilizing acknowledgment messages and timeout mechanisms to manage retransmissions efficiently.
