What is the purpose of a parity bit ?

  • A.To increase transmission speed
  • B.To detect errors in transmitted data
  • C.To compress the data
  • D.To address a memory location

Answer: C

Correct answer: To detect errors in transmitted data

A parity bit is appended so that the total number of 1s is always even or always odd, letting the receiver spot a single flipped bit. It detects an odd number of errors but cannot say which bit changed, nor correct it.
