Examples
-
The software automatically performs a cyclic redundancy check to ensure the data is error-free.
-
When storing important files, a cyclic redundancy check helps verify their integrity during transfers.
-
Error detection is improved by using a cyclic redundancy check (CRC) rather than a simple bus parity check.
Academic text (1996) -

Morphology
cyclic + redundancy + check
The parts 'cyclic' (repeating), 'redundancy' (extra data) and 'check' (verify) provide a clear partial clue—one can infer it is some kind of verification that uses redundant, repeating data. However, the precise technical sense (an algorithmic checksum used to detect storage/transmission errors) is specialized and would not be fully predictable to an average B1 learner, so it is only partially transparent.
Etymology
Cyclic redundancy check comes from the way engineers make a short extra code that repeats parts of the data in a loop (the redundancy and cyclic parts) and then use that code to check the information. If the extra code does not match later, it shows there was an 'error' or 'data corruption', so the phrase refers to a way to find changed or broken data.
