1. parity checknoun

   The act or process of testing whether a byte or other data structure has an even or odd number of bits set to the value of 1; -- it is used primarily to detect errors in data, especially in memory banks or in data transmitted over a communications line. The parity can be changed by assigning one bit in each data structure as the parity bit, so that the total number of bits set to the value of 1 is odd (odd parity) or even (even parity). If parity is used for error checking the writing and reading systems must first agree on which type of parity (odd or even) to use; if the reading system detects a deviation from the agreed parity, it signals an error, to be handled by the error-handling processes of the system.

1. parity check

   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.

1. parity check

   Parity check is a method used in computing to check the accuracy of transmitted or stored digital data. It involves adding an extra bit, known as a parity bit, to the data to make the total number of 1-bits either odd (for odd parity), or even (for even parity). The receiving device checks the parity and if it doesn't match, an error is detected. This approach can detect single bit errors and is used in various forms of data communication and storage systems.
