Explanation:
Detailed explanation-1: -Parity Bits The parity check is done by adding an extra bit, called parity bit, to the data to make the number of 1s either even or odd depending upon the type of parity. The parity check is suitable for single bit error detection only. Even Parity − Here the total number of bits in the message is made even.
Detailed explanation-2: -Which error detection method consists of just one redundant bit per data unit? Explanation: A parity checker is an error detection method used for the purpose of detecting errors that may have been incorporated during transmission. Simple parity check method consists of just one redundant bit per data unit.
