• A. Central Processing Unit
• B. Random Access Memory
• C. Graphics Processing Unit
• D. Read-Only Memory

Answer: (A)

The brain of a computer that runs programs is the central processing unit. It carries out instructions by following a fetch-decode-execute cycle: it fetches an instruction from memory, interprets what needs to be done, and then executes it, using its arithmetic logic unit for calculations and logical decisions. The control unit coordinates these steps, while registers and caches hold data and intermediate results to keep things moving quickly. Memory like RAM provides the space to store data and instructions while the CPU works on them, but it doesn’t perform the execution itself. ROM stores fixed firmware and isn’t involved in running general programs, and a graphics processing unit focuses on rendering images and handling parallel tasks rather than general instruction execution. So, the processor is what actually drives and coordinates the execution of instructions.
