Question : What is used to identify whether a data word has an odd or even number of 1's ?
Option 1: Carry bit
Option 2: Sign bit
Option 3: Zero bit
Option 4: Parity bit
Correct Answer: Parity bit
Solution : The correct option is - Parity bit
The term "parity bit" is used to describe whether a data word contains an odd or an even number of 1s. The number is "even parity" if it has an even number of 1-bits, and it has "odd parity" if it has an odd number. An integer's evenness or oddness is defined by its parity. For the purpose of detecting errors, a block of data is given a parity bit, which is a check bit. It is applied to verify the data's accuracy.
