A parity bit is a single bit added to a binary data transmission.
Types of parity bit
1. Even parity -- Even parity means the number of 1's in the given word including the parity bit should be even (2,4,6,....).
- It is used to indicate if whether the 0's and 1's within that data transmission is an even or odd number.
- The parity bit is used in parity error checking to find errors that may occur during data transmission.
1. Even parity -- Even parity means the number of 1's in the given word including the parity bit should be even (2,4,6,....).
2. Odd parity -- Odd parity means the number of 1's in the given word including the parity bit should be odd (1,3,5,....).
- Parity checking at the receiver can detect the presence of an error if the parity of the receiver signal is different from the expected parity.
- Parity of the transmitted signal is always going to be "even" and if the received signal has an odd parity.
