Selective Repeat Automatic Repeat reQuest (SR-ARQ) is a specific error control protocol used in data communication to ensure reliable delivery of packets over a network. It is an extension of the Automatic Repeat reQuest (ARQ) protocol and is designed to improve efficiency in scenarios where packets can be received out of order or lost during transmission.
