ASCII Table

ASCII (American Standard Code for Information Interchange) is a character encoding using 7 bits per character. Its history comes from the development of connecting computers (terminals) to teleprinters which required some standardized way to send and receive data as well as a way to control data flow. As a result, ASCII contains a bunch of control characters in the lower set.

Terminals convert keys from your keyboard into ASCII. The 5 lower bits of the character set mapped to a key on the keyboard. The 6th and 7th bit are set to 1 by default and are cleared the shift key and control key, respectively.

Your terminal will automatically convert specific key combinations into the appropriate character (eg. pressing Shift-1 or '!' sends the appropriate ASCII character). The terminal can also send the appropriate control character with the control modifier key. For example, pressing Ctrl-i, ^I, sends a horizontal tabulation (HT) or tab control character.
