Cyclic redundancy checks (CRCs) are a common method used to verify the integrity of data transmitted over a network. It works by performing a mathematical calculation on the data and sending this CRC value along with the data itself. The receiver then performs the same calculation and compares the result with the transmitted CRC value. If the values match, the data is considered intact; if not, this indicates that an error has occurred in transmission. Other listed terms do not pertain specifically to error detection in data transmissions.
