What is used to identify whether a data word has an odd or even number of l's ?

Options

A. Carry bit
B. Sign bit
C. Zero bit
D. Parity bit

Answer

D

Explanation

Parity bit is a term used to identify whether a data word has an odd or even number of l.s. If a data word contains an odd number of l.s, the word is said to have odd parity. The binary word 0110111 with five l.s has odd parity. The binary word 0110000 has an even number of l.s (two), so it has even parity.
