ASCII character table

The ASCII character table (American Standard Code for Information Interchange) is a standardized table that assigns a unique numerical code to each printable and non-printable character used in computers and communication devices.

ASCII characters range from value 0 to value 127 and include uppercase and lowercase letters, numbers, punctuation marks, and special characters such as spaces, tabs, and control command placeholders. Each character is represented by a unique decimal number, which can be used to store and represent it in digital format.

This table was developed in the 1960s as a standard to ensure compatibility and interoperability between various computer and communication devices. Although it was later extended to include characters not present in the first 128 (extended ASCII), the table of the first 128 characters remains the fundamental part of the ASCII standard.
