What is Odd Parity Check?
Odd parity, on the other hand, functions similarly but ensures that the total number of ones in the data, including the parity bit, is odd. If total number of 1 in the given binary string are even then 1 is appended to make the total count of 1 as odd else 0 is appended.
Case 1: When data bits contain even number of 1. So, we need to append parity bit as 1 to make odd number of 1.
Case 2: When data bits contain odd number of 1. So, we need to append parity bit 0.
How Even Parity is Different From Odd Parity?
A parity is an error coding method to find errors in digital data. A parity bit is an extra bit which is added in binary message to make total number of 1’s either even or odd. While reading or receiving the data parity check is made to find the errors in data. It is used for error detection in the original data at the receiver side and correcting the data. Parity word denotes the number of 1’s in binary string. There are two parity systems: even or odd. Even parity and odd parity are two methods which are used in data transmission to ensure the integrity of transmitted data. Both methods involve adding an extra bit to the data being transmitted, which is called parity bit, which is used for error detection.
