Which statement defines the motherboard?

• A. The primary processing unit.
• B. A portable storage device.
• C. A type of memory module.
• D. The system board and the main circuit board of the computer.

Answer: (D)

The motherboard is the system board—the main circuit board that everything connects to. It acts as the central hub inside a computer, hosting the CPU socket, memory slots, expansion cards, storage interfaces, and various controllers. It provides the pathways that let the processor, memory, storage devices, and peripherals communicate with one another, and it distributes power to all components. In short, the motherboard ties all the parts together and sets how they interact through its buses and connectors. The other options describe an individual part—the CPU, a portable storage device, or a memory module—while the motherboard is the single board that links and coordinates all of them.
