When a key is pressed on the keyboard, which standard is used for converting the keystrokes into the corresponding bits?

The correct answer is ANSI.

• Explanation: ANSI, the American National Standards Institute, is an organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States. It approved the ASCII standard, which is widely used for converting keystrokes into corresponding bits. Therefore, when referring to a standard used for this purpose, an 'ANSI standard' (like ASCII) is often implied.
• Why other options are false:
• B (ASCII): While ASCII is the specific character encoding standard, ANSI is the body that approved and standardized it. The question asks for 'which standard', and 'ANSI' can refer to standards approved by ANSI.
• C (EBCDIC): EBCDIC (Extended Binary Coded Decimal Interchange Code) is another character encoding standard, primarily used by IBM mainframe computers, not general keyboards.
• D (ISO): ISO (International Organization for Standardization) is an international standards body, distinct from ANSI, though they often collaborate.
