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

• A. Manages network security policies.
• B. Handles power management for peripherals.
• C. Executes instructions and performs calculations as directed by software.
• D. Stores long-term data securely.

Answer: (C)

The CPU’s main function is to execute instructions and perform calculations as directed by software. It acts as the brain of the computer, repeatedly fetching instructions from memory, decoding what those instructions mean, and then carrying them out using its internal components. This includes performing arithmetic and logical operations, moving data around within the system, and coordinating with memory and input/output devices to run programs. When you run a program, the CPU processes the steps the software specifies, whether it’s adding numbers, deciding which branch to take, or transferring data between components. Other options describe tasks handled by other parts of the system. Network security policies are managed by software and security systems, not the CPU’s core function. Power management for peripherals is handled by the operating system and hardware power-management features. Storing long-term data securely is the job of storage devices and file systems, with the CPU typically acting as the conductor that moves data to and from storage during processing.
