Parity bit vs checksum

Web20 Nov 2016 · Parity, in general, means whether an integer is even or odd. If we are talking about the parity of a string of bits (as in our case) then parity refers to the parity of the sum of the bits, or in other words whether the number of 1s in the string is even or odd.
