ASCII Table

What is ASCII ?

ASCII (pronounced: /ˈæski/ ass-kee[1], American Standard Code for Information Interchange) is a computer coding system based on the Latin alphabet. It is primarily used for displaying modern English. ASCII was first published as a standard specification in 1967, and the last update was in 1986.

What characters are in ASCII ?

So far, a total of 128 characters have been defined; among them, 33 characters cannot be displayed (some terminals provide extensions that allow these characters to be displayed as 8-bit symbols such as smiley faces and playing card suits), and most of these 33 characters are obsolete control characters.

The main purpose of control characters is to manipulate processed text.

Outside of the 33 characters, there are 95 displayable characters.

The blank character produced by pressing the space key on the keyboard also counts as one displayable character (displayed as a blank space).

What does the ASCII code means for a character ?

Each character in the ASCII standard is represented by a unique number between 0 and 127. These numbers are known as ASCII codes. For example, the ASCII code for the uppercase letter 'A' is 65, and for the lowercase 'a', it's 97. These codes are used by computers to understand and process text data. ASCII codes are especially important in programming and web development, as they allow for the consistent representation and handling of text across different systems and platforms.
