ASCII (American Standard Code for Information Interchange) is a standard character encoding system used to represent text in computers and communication devices. The original ASCII standard defines 128 different characters, making Option D the correct answer.
The ASCII character set includes uppercase and lowercase English letters (A–Z, a–z), digits (0–9), punctuation marks, mathematical symbols, and control characters such as Enter, Tab, Backspace, and Line Feed. Each character is represented by a unique 7-bit binary code, allowing a total of 128 (2⁷) different character combinations.
Many people confuse Standard ASCII with Extended ASCII. Standard ASCII contains 128 characters, while Extended ASCII uses 8 bits and supports 256 characters by adding extra symbols, accented letters, and graphical characters. However, when an MCQ simply asks about ASCII, it refers to the original 7-bit ASCII standard, whose character set contains 128 characters.
