What is one advantage of using ASCII rather than Baudot code?
- A It includes both upper and lower case text characters in the code
- B ASCII includes built-in error correction
- C ASCII characters contain fewer information bits
- D The larger character set allows store-and-forward
Correct answer: A — It includes both upper and lower case text characters in the code. From the official ISED question bank, verified word for word.
Why
ASCII uses more bits per character than Baudot, which allows it to represent both upper and lower case letters, giving text much better readability. The full explanation — and one for every question — is in Pro.
