What role does the CPU play in a computer?

The CPU, or Central Processing Unit, is often referred to as the "brain" of the computer because it is responsible for executing instructions and processing data. It handles all the calculations, logical operations, and decision-making tasks essential for running programs and performing operations. The CPU interprets and executes instructions from the computer's memory, coordinating and controlling the other hardware components. This central role allows it to process inputs and produce outputs efficiently, making it a critical component for any computing task.

While the CPU plays a vital role in the operation of a computer, other components perform different functions. For instance, long-term data storage is handled by storage devices like hard drives or SSDs, which is why one option refers to permanent data storage, and power is managed by the power supply and not the CPU itself. Network connections are overseen by network interface cards, which manage the communication between devices on a network, further differentiating their responsibilities from that of the CPU. Understanding the unique contributions of each of these components helps clarify the CPU's specific function within the computer system.
