Alphanumeric text representation used in computers, designed without graphical symbols for easier transmission and display on early digital devices.
In the early 1960s, a groundbreaking character encoding standard was developed to facilitate a common language for information interchange in computing. This standard, known as ASCII, was born in 1963.
ASCII, an acronym for American Standard Code for Information Interchange, is a fundamental system that computers use to represent and exchange text data. It consists of 128 characters, including printable characters and control characters.
Each character in the ASCII table is assigned a specific binary value, using a 7-bit binary system. For instance, the lowercase letter "m" can be represented in binary as 01101101, in decimal as 109, in hexadecimal as 6D, and in octal as 155.
The primary purpose of ASCII was to create a universal system for computer systems to communicate effectively. This was achieved by including uppercase letters, lowercase letters, numeric characters, punctuation marks, and control characters in the ASCII set. The first 32 ASCII codes (0-31) are designated as control characters, which perform specific functions in computer systems.
In the late 1960s, the American National Standards Institute (ANSI) formalised ASCII, solidifying its role as the backbone of text data representation in computing.
As technology evolved, the need for a more extensive character set emerged. This led to the development of Extended ASCII, which accommodates a total of 256 characters.
In modern computing, ASCII continues to be a crucial standard, particularly in environments like Windows PowerShell. PowerShell offers commands like to display ASCII codes, allowing for a deeper understanding of the data being manipulated.
Moreover, with the advent of global communication, the need for a character encoding standard that encompasses a vast array of characters from multiple languages and symbol sets arose. This need was met by Unicode, which is compatible with ASCII while extending its potential for global communication.
Popular encodings like UTF-8, UTF-16, and UTF-32 ensure compatibility with ASCII while offering the ability to represent characters from virtually any writing system.
ASCII art, a creative application of the ASCII set, uses characters from the ASCII set to create images and designs. This art form has been a popular way to express creativity within the constraints of the ASCII character set.
In conclusion, ASCII, developed in the early 1960s, has played a pivotal role in the development of computing. Its influence can still be seen in modern computing, making it a cornerstone of the digital world we live in today.
