    A communication technique called Automatic Repeat reQuest (ARQ) is used in computer networks to guarantee the accurate and error-free delivery of data. ARQ mechanisms function by identifying transmission problems and demanding that the offending packets be retransmitted. The following are some benefits of employing ARQ in computer networks: 1.

    Aug 9, 2024 · What is Stop and Wait ARQ? The Stop and Wait ARQ protocol sends a data frame and then waits for an acknowledgment (ACK) from the receiver. The ACK indicates that the receiver successfully received the data frame. After receiving the ACK from the receiver, the sender delivers the next data frame.
