Which component is part of the system unit? Power supply Keyboard Microphone Printer

The correct answer is: Power supply.The system unit, also known as the computer case or tower, is the main part of a computer system that houses the internal components. It typically includes the motherboard, central processing unit (CPU), random access memory (RAM), storage devices (such as hard drives or solid-state drives), power supply, and other essential components.The power supply is responsible for converting the alternating current (AC) from the wall outlet into direct current (DC) that the computer's internal components can use. It ensures that the computer receives the necessary power to function properly.On the other hand, the keyboard, microphone, and printer are external peripherals that are not part of the system unit. They are connected to the computer through various ports and interfaces but are not housed within the system unit itself.
