Bit parity involves adding an extra bit (the parity bit) to a string of binary code to ensure that the total number of 1-bits in the string is even or odd. This extra bit is typically added to the end of the data packet, not the front. The purpose of this is to make the total count of 1s either even (even parity) or odd (odd parity), which can be used for error detection.
