How many bits per character does ASCII use?

Explanation:
ASCII uses seven bits to represent each character, giving 128 possible symbols (letters, digits, punctuation, and control codes). In practice, computers store characters in an 8-bit byte, leaving the eighth bit unused or used for parity or extended sets, but the standard ASCII specification itself uses 7 bits. So seven bits is the correct answer.
