 Longitudinal redundancy check

A Longitudinal Redundancy Check (LRC) is a type of error detection method used in digital communication and data storage to ensure the integrity of transmitted or stored data. It is particularly useful for detecting errors that may occur during data transmission over a noisy communication channel or during storage. The LRC works by calculating a checksum for each row of data, which is then combined to create a single redundancy byte that represents the overall data.
