ASCII - definition
American Standard Code for Information Interchange is referred to as ASCII. It is a type of character encoding that gives each character in the English language a special numeric code, as well as some control codes that may be used to operate printers and computers. Since its initial publication in 1963, the ASCII standard has been widely adopted as a fundamental encoding standard in the computer industry.
The 128 characters in the ASCII standard include capital and lowercase letters, numbers, punctuation, and unique control characters like carriage return, line feed, and backspace. A 7-bit binary integer is used to represent each character, giving a total of 128 potential characters. There are 256 potential characters in Extended ASCII, which adds an extra 128 by using 8-bit binary integers.
Although Unicode, a more complete character encoding standard that can represent characters from various languages and scripts, has largely replaced ASCII, it is still widely used today. However, because of its simple, standardized character set, ASCII is still a crucial encoding standard for older systems and some applications.
