American Standard Code for Information Interchange (ASCII) is a coding system adopted in 1963 and used to represent all text characters and control codes a computer is capable of producing.[1] ASCII is the built-in binary code for representing characters in all computers except IBM mainframes. Originally developed for communications, ASCII uses only seven bits per character, providing 128 combinations that include upper and lower case alphabetic letters, the numeric digits and special symbols such as the $ and %.
