Which component provides electrical power to the computer system?

• A. RAM
• B. Input Device
• C. Motherboard
• D. Power Supply

Answer: (D)

The main idea is identifying the component that provides electrical power to the whole system. The power supply takes in AC from the wall and converts it into stable DC voltages that all parts of the computer use. It feeds the motherboard and other components with the required rails (such as +12V, +5V, and +3.3V), and it also helps regulate voltage and protect the system from power issues. Without this source, nothing in the computer could run. RAM is memory that needs power to operate and keep data, but it does not generate or supply power to the system. An input device like a keyboard or mouse consumes power from the system; it does not supply power. The motherboard is the main circuit board that connects components and distributes signals, but it relies on the power supply to provide the actual power. It does not generate power itself. So, the component that provides electrical power to the computer system is the power supply.
