Parity Bit

A parity bit is a simple error-checking tool used in digital communication. It's an extra bit added to a string of binary data (0s and 1s) to help detect errors during transmission. Depending on the chosen method, the parity bit ensures that the total number of 1s in the data is either always even (even parity) or always odd (odd parity). When the data is received, the system checks the parity bit along with the data. If the parity doesn't match the expected pattern, it indicates that an error may have occurred during transfer.
