Which code is commonly used for character representation in computing?

The correct response is based on the widespread use of ASCII, which stands for American Standard Code for Information Interchange. ASCII is a character encoding standard that uses numerical values from 0 to 127 to represent characters, including letters, digits, punctuation marks, and control characters. Each character is mapped to a specific number, effectively enabling computers to handle and display text.

ASCII's importance in computing stems from its ability to maintain compatibility across different systems and platforms, particularly in text-based data communication. It forms the foundation for more complex encoding systems and has been pivotal in the development of modern programming and markup languages.

Other coding systems, such as Binary Code, are more general forms of number representation rather than character representation specifically. Binary Coded Decimal is a way of encoding decimal numbers in binary form but does not define character representation. Gray Code is primarily used in error correction in digital communications and does not relate to text characters either. Therefore, ASCII stands out as the most relevant and widely used code for character representation in computing.
