Parity

(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.

Bit(s) used to determine whether a block of data has been altered. Rationale: Term has been replaced by the term “parity bit”.

functional equality

(physics) parity is conserved in a universe in which the laws of physics are the same in a right-handed system of coordinates as in a left-handed system

(mathematics) a relation between a pair of integers: if both integers are odd or both are even they have the same parity
