Cyclic Redundancy Check

/ˌsiː-ɑːr-ˈsiː/

n. “The digital fingerprint that checks your data for errors.”

CRC, short for Cyclic Redundancy Check, is an error-detecting code used in digital networks and storage devices to detect accidental changes to raw data. By applying a mathematical algorithm to the data, CRC generates a fixed-size checksum (also called a CRC value) that can be used to verify data integrity during transmission or storage.

Key characteristics of CRC include:
