What is the primary function of the CPU in a computer system?

• A. Executes instructions and performs arithmetic and logic operations, and coordinates the activities of other components.
• B. Stores data permanently.
• C. Manages network connections.
• D. Provides power to the motherboard.

Answer: (C)

The CPU’s main role is to execute instructions and perform arithmetic and logic operations, while coordinating the activities of other components. It fetches instructions from memory, decodes them, and carries out the required operations, using its arithmetic logic unit and registers. In doing so, it also sends control signals and manages data flow between memory, input/output devices, and peripherals, effectively orchestrating how the system works together to complete tasks. Storing data permanently is the job of storage devices like hard drives and SSDs, not the CPU. Managing network connections is handled by network hardware and software, and providing power to the motherboard comes from the power supply unit.
