ASCII Table

October 17, 2018

ASCII is the acronym for the American Standard Code for Information Interchange. These codes are simply numerical representations of a character. Computers can only understand numbers, so there is a need for a encoding characters to numbers.

The table below contains the code definitions for 128 characters, most of which are printable characters of the alphabet. The non-alphabet characters are referred to as control characters.

Control characters cannot be printed but instead control how text is processed.
