parity
n 1: (obstetrics) the number of liveborn children a woman has
delivered; "the parity of the mother must be considered";
"a bipara is a woman who has given birth to two children"
[synonym: {parity}, {para}]
2: (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"
3: (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 [synonym: {parity bit}, {parity}, {check bit}]
4: (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 [synonym: {parity},
{conservation of parity}, {space-reflection symmetry},
{mirror symmetry}]
5: functional equality

Parity \Par"i*ty\, n. [L. paritas, fr. par, paris, equal: cf. F.
parit['e]. See {Pair}, {Peer} an equal.]
1. 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." --De Quincey.
[1913 Webster]

Equality of length and parity of numeration. --Sir
T. Browne.
[1913 Webster]

2. Specifically: (Finance) Equivalence in value to the
currency of another country.
[PJC]

3. (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.
[PJC]

4. (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.
[PJC]

5. (Med.) The condition of having borne a child or children,
alive or dead.
[PJC]

6. (Math.) The property of being even or odd; as, 3 has odd
parity, but 6 has even parity.
[PJC]

7. Hence: (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}.
[PJC]
