What is ASCII character code?

ASCII stands for American Standard Code for Information Interchange. It was developed by ANSI (American National Standards Institute).

It is a set of decimal coded value for all basic printable and non-printable characters. For example - A is represented as 65 in ASCII standard. Similarly, there exists an integer value to represent every printable and non-printable character.

ASCII exists in two versions 7-bit ASCII and 8-bit ASCII. The first 7-bit version of ASCII contains 128 characters (including upper and lower case alphabets, digits, punctuations, special characters, non-printable and control characters). It uses 7 bit in memory to represent single character. Later 7 bit variant of ASCII was extended to 8 bit and is popularly known as Extended ASCII. It uses 8 bit to represent a character and can represent upto 255 characters.
