ASCII codes represent text in computers, telecommunications equipment, and other devices that use text. ASCII codes are represented by seven-bit numbers, each of which can represent one of 128 different characters. The ASCII character set includes letters of the English alphabet, numbers, punctuation marks, and control codes.
