The processing part of a computer has two categories: CPU and GPU. Which statement best describes their roles?

• A. They are types of storage devices.
• B. They are input devices.
• C. They are the main processing components.
• D. They are peripheral devices.

Answer: (C)

CPU and GPU are the main processing components inside a computer. They perform the actual computations that run programs. The CPU handles general-purpose tasks, executing instructions, performing arithmetic and logic, and directing other parts of the system. The GPU specializes in parallel processing, handling many calculations at once, which is especially useful for graphics rendering and other tasks that can be broken into many small, concurrent operations. They aren’t storage devices like RAM or a hard drive, they aren’t input devices like a keyboard or mouse, and they aren’t peripheral devices. So, describing them as the main processing components captures their essential role in driving computation.
