    • n parity (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
    • n 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
    • n parity (mathematics) a relation between a pair of integers: if both integers are odd or both are even they have the same parity; if one is odd and the other is even they have different parity "parity is often used to check the integrity of transmitted data"

    • Parity (Physics) A property assigned to elementary particles, conceptualized as a form of symmetry, representing the fact that no fundamental distinctions can be observed between right-handed and left-handed systems of particles in their interactions, and supported by the typical observation that the total parity of a system is unchanged as particles are created or annihilated; however, certain interactions involving the weak force have been shown to violate the principle of conservation of parity.
    • Parity (Physics) A property of the wave function of a system, which takes the value of +1 or -1, indicating whether the value of the wave function changes sign if each of the variables of the system is replaced by its negative.
    • Parity (Finance) Equivalence in value to the currency of another country.
    • Parity (Med) The condition of having borne a child or children, alive or dead.
    • Parity (Math) The property of being even or odd; as, 3 has odd parity, but 6 has even parity .
    • Parity (Computers) The property of having an even or odd number of bits set to the value of 1 (as opposed to 0); -- applied to bytes or larger groups of bits in a data structure. It is used mostly in the process of parity checking. The parity of a data structure can be changed by changing the value of the parity bit.
    • Parity The quality or condition of being equal or equivalent; a like state or degree; equality; equivalence; close correspondence; analogy; as, parity of reasoning. "No parity of principle.""Equality of length and parity of numeration."
