Noun
  1. (obstetrics) the number of liveborn children a woman has delivered (synset 114070653)
    "the parity of the mother must be considered"; "a bipara is a woman who has given birth to two children"

    is a type of: gestation, maternity, pregnancy - the state of being pregnant; the period from conception to birth when a woman carries a developing fetus in her uterus
    same as: 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 (synset 113812345)
    "parity is often used to check the integrity of transmitted data"
    referred to in: math, mathematics, maths - a science (or group of related sciences) dealing with the logic of quantity and shape and arrangement
    is a type of: mathematical relation - a relation between mathematical expressions (such as equality or inequality)
    subtypes:
    • evenness - the parity of even numbers (divisible by two)
    • oddness - the parity of odd numbers (not divisible by two)
  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 (synset 113646953)
    referred to in: computer science, computing - the branch of engineering science that studies (with the aid of computers) computable processes and structures
    is a type of: bit - a unit of measurement of information (from binary + digit); the amount of information in a system having two equiprobable states
    same as: check bit, parity 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 (synset 106114921)
    referred to in: natural philosophy, physics - the science of matter and energy and their interactions
    is a type of: conservation - (physics) the maintenance of a certain quantities unchanged during chemical reactions or physical transformations
    same as: conservation of parity, mirror symmetry, space-reflection symmetry
  5. Functional equality (synset 104755666)
