(n): the state of being pregnant; the period from conception to birth when a woman carries a developing fetus in her uterus
(n): (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
(n): a relation between mathematical expressions (such as equality or inequality)
(n): (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): a unit of measurement of information (from binary + digit); the amount of information in a system having two equiprobable states
(n): (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): (physics) the maintenance of a certain quantities unchanged during chemical reactions or physical transformations
(n): functional equality
(n): essential equality and interchangeability
