Cyclic Redundancy Check (CRC): A method for detecting errors in digital data using a mathematical algorithm to generate a checksum known as a CRC value. This value is compared with a newly calculated CRC upon data retrieval or transmission to verify data integrity. If the values differ, it signals data corruption. CRC is widely used for error detection in computer networks, storage media, and various communication protocols, sometimes facilitating error correction.
