Cyclic Redundancy Check (Code)

(C-R-C)

One of many mathematical ways of checking data for corruption. For example, a CRC calculation might be performed on data before sending it to someone else. They then make the same calculation and compare the before and after results. If the same, then the data is likely accurate. A checksum has a similar function but is far simplier in execution. CRCs typically involve using bit shifts and/or division operations. CRCs are not absolutely accurate. They will detect some corruption but multiple types of corruption of a single dataum could, potentially, cancel each other out so the CRC would say there are no errors.
