Which term is used for a representation that lists inputs and outputs, often used to analyze circuits?

• A. High-level language
• B. Low-level language
• C. Truth table
• D. Logic circuit

Answer: (C)

The concept here is a representation that lists inputs and outputs to analyze circuits. The term that fits best is truth table because it explicitly lists every possible combination of input values and the corresponding output for a logic function. This makes it a precise tool for understanding how a circuit behaves in all scenarios, without needing to build it physically. It’s especially handy for checking logic, debugging designs, and later helping to derive a simplified boolean expression. In contrast, a high-level language describes algorithms in readable code, not the detailed input–output behavior of a circuit. A low-level language expresses instructions close to machine code, again focusing on computation rather than mapping all input patterns to outputs. A logic circuit is the actual arrangement of gates and connections, a structural representation rather than a table that enumerates input-output cases.
