Which of the following correctly describes a parity bit?
AA bit added to make the total number of 1s even or odd
BA bit used to encrypt data
CA bit that compresses the data size
DA bit that stores the checksum value
Step-by-Step Solution
Solution:

  1. Step 1: Define parity bit function

    A parity bit is added to data to ensure the total number of 1s is either even or odd, helping detect errors.

  2. Step 2: Match options with definition

    A bit added to make the total number of 1s even or odd matches this definition exactly; other options describe unrelated functions.

  3. Final Answer:

    A bit added to make the total number of 1s even or odd -> Option A

  4. Quick Check:

    Parity bit = Even/Odd 1s check [OK]
Quick Trick: Parity bit counts 1s to check even or odd [OK]
Common Mistakes:
MISTAKES
  • Thinking parity bit encrypts data
  • Confusing parity bit with checksum
  • Assuming parity bit compresses data
