What is ASCII – A Complete Guide to Generating ASCII Code
The American Standard Code for Information Interchange, or ASCII, is a character encoding standard that has been a foundational element in computing for decades. It plays a crucial role in representing text and control characters in digital form.
Historical Background
ASCII has a rich history, dating back to its development in the early 1960s. Originating from telegraph code and Morse code, ASCII emerged as a standardized way to represent characters in computers, facilitating data interchange.
Importance in Computing
ASCII’s significance in computing lies in its universality. It provides a standardized method for encoding characters, allowing seamless communication and data exchange across diverse computing systems.
