redundancy check
Definition
Noun: A redundancy check is a system or method used to verify the accuracy of data or to detect errors in computer operations. It involves adding extra, redundant information to the data so that errors can be identified or corrected.
Usage
This term is used in computing and data communication contexts. It describes a fundamental technique for ensuring data integrity. - It is often part of a larger system's error detection or correction protocols. - The "check" refers to the verification process itself, while "redundancy" refers to the extra bits of data added for this purpose.
Examples
Advanced Usage
- Cyclic Redundancy Check (CRC): A specific, powerful type of redundancy check algorithm widely used in network communications and storage devices to detect accidental changes to raw data.
- The file transfer uses a 32-bit Cyclic Redundancy Check to guarantee data integrity.
Variants and Related Words
- Error Detection and Correction (EDAC): A broader field that encompasses redundancy checks.
- Parity Check: A simple type of redundancy check using a single parity bit.
- Checksum: A value used to verify data integrity, often calculated through a form of redundancy check.
Synonyms
- Error check
- Data validation (in a specific technical sense)
- Integrity check
Related Phrases
- Perform a redundancy check: To execute the verification process.
- The software will perform a redundancy check before finalizing the write operation.
- Redundancy check bit: The specific extra bit(s) added for the check.
- The redundancy check bits are appended to the end of the data packet.
Noun
-
