### Princeton's WordNet

parity bit, parity, check bitnoun

(computer science) a bit that is used in an error detection procedure in which a 0 or 1 is added to each group of bits so that it will have either an odd number of 1's or an even number of 1's; e.g., if the parity is odd then any group of bits that arrives with an even number of 1's must contain an error

### GCIDE

parity bitnoun

The bit within a data structure which is assigned a value of 1 or 0 so as to make the parity of the data structure odd or even. Data structures may or may not have parity bits, dpending on whether the system does or does not perform parity checking. The most commonly used parity bit is the eigth (higher-order) bit of a byte, which is used when data transmission uses only the 7 lower-order bits of each byte as significant data; some memory systems use a ninth bit as a parity bit for each eight bits (one byte) of significant data in memory.

### Wiktionary

parity bitnoun

A bit (binary digit) used to indicate whether the number of bits in a given set with value of one is even or odd. Parity bits are used as a simple error detection code.

### Wikipedia

Parity bit

A parity bit, or check bit, is a bit added to a string of binary code. Parity bits are a simple form of error detecting code. Parity bits are generally applied to the smallest units of a communication protocol, typically 8-bit octets (bytes), although they can also be applied separately to an entire message string of bits. The parity bit ensures that the total number of 1-bits in the string is even or odd. Accordingly, there are two variants of parity bits: even parity bit and odd parity bit. In the case of even parity, for a given set of bits, the bits whose value is 1 are counted. If that count is odd, the parity bit value is set to 1, making the total count of occurrences of 1s in the whole set (including the parity bit) an even number. If the count of 1s in a given set of bits is already even, the parity bit's value is 0. In the case of odd parity, the coding is reversed. For a given set of bits, if the count of bits with a value of 1 is even, the parity bit value is set to 1 making the total count of 1s in the whole set (including the parity bit) an odd number. If the count of bits with a value of 1 is odd, the count is already odd so the parity bit's value is 0. Even parity is a special case of a cyclic redundancy check (CRC), where the 1-bit CRC is generated by the polynomial x+1.

parity bit

A parity bit is a binary digit used in computer systems for error detection. It is added to a set of binary code to ensure that the total number of 1-bits in the set is either always even (even parity) or always odd (odd parity). This allows identification of errors during data transmission or storage.

Parity bit

A parity bit, or check bit, is a bit added to the end of a string of binary code that indicates whether the number of bits in the string with the value one is even or odd. Parity bits are used as the simplest form of error detecting code. There are two variants of parity bits: even parity bit and odd parity bit. In case of even parity, the parity bit is set to 1, if the number of ones in a given set of bits is odd, making the number of ones in the entire set of bits even. If the number of ones in a given set of bits is already even, it is set to a 0. When using odd parity, the parity bit is set to 1 if the number of ones in a given set of bits is even, making the number of ones in the entire set of bits odd. When the number of set bits is odd, then the odd parity bit is set to 0. Even parity is a special case of a cyclic redundancy check, where the 1-bit CRC is generated by the polynomial x+1. If the parity bit is present but not used, it may be referred to as mark parity or space parity.
