parity

noun

1. Equality; comparability of strength or intensity.

2. Senses related to classification into two sets.

3. mathematicsA set with the property of having all of its elements belonging to one of two disjoint subsets, especially a set of integers split in subsets of even and odd elements.

   “Parity is always preserved in such operations.”

4. mathematicsThe classification of an element of a set with parity into one of the two sets.

13. (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

14. (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

    Similar: conservation of parity, space-reflection symmetry, mirror symmetry
