What is the relationship between a circuit and computation?

• A. Circuits can perform logical and mathematical operations
• B. Circuits store large amounts of data like libraries
• C. Circuits are only used for power
• D. Circuits cannot process data

Answer: (A)

Computation is done by circuits that transform input signals into output signals using logical rules. Digital circuits are built from logic gates that perform basic operations like AND, OR, and NOT. By wiring many gates together, circuits can implement more complex operations, including comparisons and arithmetic, which is how a CPU carries out instructions. This is why circuits are able to perform logical and mathematical operations—their main role in computation is to manipulate data through these operations. The other statements miss the mark: circuits aren’t primarily for storing lots of data, they aren’t only for power, and they can process data.
