As nouns, parity is a hyponym of bit; that is, parity is a word with a more specific, narrower meaning than bit:

bit: a unit of measurement of information (from binary + digit); the amount of information in a system having two equiprobable states
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

Other hyponyms of bit include check bit, parity bit.
