What is the ASCII Table?

The ASCII Table (American Standard Code for Information Interchange) is a character encoding standard used in computers and electronic devices. Developed in the 1960s, it defines 128 unique characters (0-127) including letters, numbers, symbols and control characters. Each character is represented by a decimal number that can be converted to hexadecimal and binary. It is fundamental for programming, data communication and cross-system compatibility.
