WebA parity bit is an extra bit that is associated with a word of storage. The value of 1 or 0 is assigned to the parity bit to make the total number of 1s in the word odd if odd parity is used, and even if even parity is used. For example, the ASCII code for ‘A’ is 0100 0001. Using odd parity, it is 1 0100 0001. WebError-detection and correction schemes can be either systematic or non-systematic.
