Noun1.check bit - (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
computer science, computing - the branch of engineering science that studies (with the aid of computers) computable processes and structures
