ASCII referred as “American Standard Code for Information Interchange” is a computer coding scheme published by ISO (international Standards Organization). The codes assigned to various characters. To represent data in computer we assign a numeric code to each character of the alphabet.

Computer converts codes into binary numbers to make it understand in own language. It’s a 7 bit coding scheme. With the other special characters and control codes filled in, ASCII was published as ASA X3.4-1963, leaving 28 code positions without any assigned meaning, reserved for future standardization, and one unassigned control code.

There was some debate at the time whether there should be more control characters rather than the lowercase alphabet.
