parity check (encz) | parity check, n: |
parity check (gcide) | parity check \par"i*ty check`\, n. (Computers)
The act or process of testing whether a byte or other data
structure has an even or odd number of bits set to the value
of 1; -- it is used primarily to detect errors in data,
especially in memory banks or in data transmitted over a
communications line. The parity can be changed by assigning
one bit in each data structure as the parity bit, so that
the total number of bits set to the value of 1 is odd (odd
parity) or even (even parity). If parity is used for error
checking the writing and reading systems must first agree on
which type of parity (odd or even) to use; if the reading
system detects a deviation from the agreed parity, it signals
an error, to be handled by the error-handling processes of
the system.
