Standard ASCII Character Codes with Decimal, Hexadecimal, and Octal Values

The table below lists the American Standard Code for Information Interchange (ASCII), a set of 7-bit codes representing commonly used character from the Latin alphabet. Introduced around 1963, ASCII, pronounced "ask-key", survives as a common character encoding for general computing.

The set of Standard ASCII character codes consists of 128 values, ranging from 00h (0d) through 7Fh (127d,) assigned to letters, numbers, punctuation marks, and commonly used special characters.

The set of Extended ASCII Character Codes also consists of 128 values and ranges from 80h (128d) through FFh (255d) representing additional special, mathematical, graphic, and foreign characters.
