What is the advantage of including parity bits in ASCII characters?
- A.Faster transmission rate
- B.Signal-to-noise ratio is improved
- C.A larger character set is available
- D.Some types of errors can be detected (correct answer)
WhyIncluding parity bits in ASCII characters lets some types of errors be detected. Including parity bits in ASCII characters gives a receiver a simple way to detect that some types of transmission errors have occurred, by checking whether the received bit pattern's parity still matches what was expected, answer D. It doesn't speed up transmission (parity bits actually add overhead), doesn't directly improve signal-to-noise ratio, and doesn't expand the available character set, those aren't what parity bits accomplish.
