What is ASCII?
ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns numbers 0-127 to letters, digits, punctuation marks, and control characters. It forms the basis of most modern text encoding systems including UTF-8. Each ASCII character is represented by a unique number, which computers store and process as binary data.
