Which statement about ASCII is used in computing?

• A. A 7-bit/8-bit character encoding standard mapping characters to numeric values.
• B. A method for rendering graphics.
• C. A protocol for secure email.
• D. A language for database queries.

Answer: (A)

ASCII is the character encoding standard used in computing to map characters to numeric values, enabling text to be stored and processed consistently. It began as a 7-bit scheme, providing 128 codes for letters, digits, punctuation, and control characters. An 8-bit extension expands this to 256 codes, allowing additional characters. This numeric mapping is what lets computers represent text in memory and transfer it between systems. It’s not a method for rendering graphics, a protocol for secure email, or a language for database queries.
