Even parity means the number of 1s in the byte is even; odd parity means the number of 1s in the byte is odd.
Even parity adds an extra bit; odd parity doesn't.
Even parity is used for error correction; odd parity is used for error detection.
Even parity is always preferred; odd parity is less reliable.
