This is a way to detect errors in data that is being transmitted in which the parity bit checks for odd numbers of 1s.
An error-checking system in which the sending device adds an extra bit set to 0 or 1 as necessary to make the total of 1 bits add up to an odd number. The receiving device adds the 1 bits and if the total is an odd number, it assumes the message came through intact.
An error-checking protocol in which the parity bit is set to 1 if the number of 1 digits in a byte adds up to an even number.
Data integrity checking in which the parity bit checks for an odd number of 1s.
Indicates that the total number of 1s in the unit of transmitted information must be odd.
