ARQ is an acronym for:
- Automatic Repeat-reQuest. It is an Error control method for data transmission in which the receiver detects transmission errors in a message and automatically requests a retransmission from the transmitter.
Usually, when the transmitter receives the ARQ, the transmitter retransmits the message until it is either correctly received or the error persists beyond a predetermined number of retransmissions.
A few types of ARQ protocols are Stop-and-wait ARQ, Go-Back-N ARQ and Selective Repeat ARQ.
