Parity Check - English Definition & Meaning

Definition

A parity check is a simple error-detection method used in computer systems to ensure data integrity. It involves adding an extra bit (the parity bit) to a data unit to make the number of 1s either even (even parity) or odd (odd parity). Think of it as a basic way to catch mistakes in transmission 💻. The receiving system recalculates the parity and compares it to the transmitted parity bit. If they don’t match, it indicates an error occurred. It's a fundamental technique for detecting single-bit errors in data storage and transmission.

Etymology

The term 'parity check' comes from 'parity,' meaning 'the state or condition of being equal, especially regarding status or pay.' In this context, 'parity' refers to the equal status of either even or odd numbers of bits. 'Check' refers to the act of verifying something. So 'parity check' literally means checking for the balance of even or odd bits. Its roots are in early computer science and data communication. It developed to detect errors during data processing.
