  • Before sending the data, the programmer implemented a parity check to verify the integrity of the information.

Examples

  • If you when you receive the packet, you check to see whether the parity check checks.

  • - You can run a parity check.

    In the Line of Fire (1993)

  • The powers of two and the parity check bits.

  • And then I will give you a methodology for working out what the parity check bits would be.

  • Error detection is improved by using a cyclic redundancy check (CRC) rather than a simple bus parity check.

    Academic text (1996)

  • The system performed a parity check to ensure the data transmission was error-free.

  • To detect any transmission errors, he added a parity check to the data packet.

Morphology

parity + check

The meaning is directly compositional: 'parity' denotes an even/odd property and 'check' means to verify, so 'parity check' literally refers to verifying parity (the evenness/oddness) of data. Although the term is technical, its sense follows straightforward combination of the constituents and is cross-linguistically paralleled, so a B1 learner who knows both words would be able to infer the meaning.

Etymology

Parity check comes from a simple idea: parity means 'even' or 'odd' and check means to test. Early computers added one extra digit and used this test to see if the number of '1's was correct, so a parity check became a basic way to find 'errors' in data.
