ASCII represents how many characters?

Explanation:
ASCII uses 7 bits to represent each character, which gives 2^7 = 128 possible values. These codes cover both the control characters (like null, bell, backspace) and the printable characters (letters, digits, punctuation). So ASCII represents 128 characters in its standard form. Some systems talk about extended ASCII using 8 bits, which allows 256 codes, but that isn’t the original ASCII standard.
