cyclic redundancy check
This term is a technical specification used almost exclusively in computer science, telecommunications, and data storage. It describes a specific mathematical process for verifying data integrity. In professional contexts, it is frequently referred to by its acronym, CRC, which is often used as a noun or an adjective (e.g., a CRC error).
Because this is a specialized technical term, it does not carry emotional connotation or register variation; it is consistently formal and precise. It is distinct from a "checksum," which is a broader category of error detection, whereas a cyclic redundancy check uses a specific polynomial division method to provide a higher probability of detecting burst errors.
Meanings
An error-detecting code used in digital networks and storage devices to detect accidental changes to raw data by applying a mathematical polynomial division to the data stream.
The system performed a cyclic redundancy check to ensure the file was not corrupted during the transfer.
