Single Parity Bit Checker VRC

The simplest and oldest error detection method. A binary digit called parity is used to indicate whether the number of bits with “1” in a given set of bits is even or odd. The parity bit is then appended to original data.
Usually used to detect transmission error . Sender adds the parity bit to existing data bits before transmission.
Receiver checks for the expected parity, If wrong parity found, the received data is discarded and retransmission is requested.
