• C. American Scientific Code for Interchanging Information
• D. American Standard Code for Interchanging Information

Answer 1

Answer:

B. American Standard Code for Information Interchange

• ASCII stands for "American Standard Code for Information Interchange." It is a character encoding standard developed in the early 1960s to represent text in computers, communication equipment, and other devices that use text. ASCII assigns a unique numeric value (from 0 to 127 in the standard 7-bit ASCII) to letters (uppercase and lowercase), digits, punctuation marks, and control characters (like carriage return and line feed).

• Key points:

  • "American" indicates its origin in the United States.

  • "Standard" means it is a widely accepted convention.

  • "Code" refers to the mapping of characters to numeric values.

  • "Information Interchange" emphasizes its role in enabling data exchange between different devices and systems.

• Because Option B exactly matches this full form, it is the correct choice.
