1. Automatic Repeat reQuest (ARQ)
Definition and Purpose
Automatic Repeat reQuest (ARQ) is a protocol used in data transmission systems to ensure reliable communication by automatically requesting the retransmission of corrupted or lost data packets. ARQ mechanisms detect errors in transmitted data and prompt the sender to resend the affected packets.
Components and Functionality
ARQ protocols involve error detection methods, such as checksums or CRCs, to identify corrupted packets. When an error is detected, the receiver sends a negative acknowledgment (NACK) back to the sender, which then retransmits the erroneous packet. Common ARQ schemes include Stop-and-Wait ARQ, Go-Back-N ARQ, and Selective Repeat ARQ.
Importance
ARQ protocols are crucial for maintaining data integrity and reliability in communication networks. They are widely used in various applications, including computer networks, wireless communication, and satellite systems.
