Error detection code can be used to detect errors during transmission. Normally the detected error cannot be corrected, but its presence is indicated.

The data and information or binary information will be transmitted on the basis of pulse-modulated signals or digital computer input or output. There will be the transmission medium that may be wires or radio waves.

There is a parity method for error detection. Where the parity method has to variations even and odd parity. Lots of systems use a parity bit to handle the bit or error detection. The binary group of data will contain the either even or an odd number of 1s. A parity is an extra bit included with a message to make the total number of 1's either odd or even.
