Question

What is the purpose of ASCII?

Short answer

Answer: The purpose of the ASCII code is to provide a standardized method for computers and electronic devices to communicate and store text information by assigning unique codes to each character. It streamlines communication and data storage and serves as the foundation for modern character encoding systems like Unicode, ensuring compatibility during global exchange of information.

Step-by-step solution

Introduction to ASCII

ASCII, which stands for American Standard Code for Information Interchange, is a character encoding standard. It was developed in the early 60s and remains prevalent today. The purpose of ASCII is to represent text in computers and other devices that handle text, allowing for the seamless exchange of information between various platforms.

Encoding Characters

ASCII assigns a unique binary code, usually 7 bits long, to represent each character. These codes range from 0 to 127, covering letters (both uppercase and lowercase), digits, punctuation marks, and some special control characters used for various purposes like moving the cursor, line breaks, or data transmission.

ASCII's Role Today

While ASCII isn't the only character encoding system in use today, it remains the foundation for many more extensive encoding systems like Unicode. Unicode includes thousands of characters for various languages and scripts, while still preserving the ASCII characters and their respective codes within its scheme to maintain compatibility during a more global exchange of information.

Conclusion

The purpose of ASCII is to create a standardized method for computers and electronic devices to communicate and store text information. By assigning unique codes to each character, ASCII streamlines communication and data storage while providing a foundation for modern character encoding systems like Unicode.
