- B. 256
- C. 512
- D. 1024
Explanation
ASCII (American Standard Code for Information Interchange) is a character encoding standard that uses 7 bits to represent 128 different characters. Each bit in the 7-bit code can be either 0 or 1, and there are a total of 2^7 (128) possible combinations of these bits. These combinations can be used to represent letters, numbers, punctuation marks, and control characters.
