Q
How many bits will be added to a data word to become a code word in simple parity check code?
AA. 1 bit
BB. 2 bits
CC. 0 bits
DD. 4 bits
Correct Answer:
A. A. 1 bit
Explanation:
Code word will have total of k+1 bits where k is the number of bits in data word. This extra parity bit helps the code word to have even number of 1s and it can be 0 or 1. Parity code is an error detecting code but doesn’t correct the errors.
