Correct Answer:
B. System Board
The motherboard is the main printed circuit board found in general-purpose computers and other expandable systems. It is also commonly known as the System Board. This name reflects its central role as the primary hub that connects and allows communication between all the computer's essential components. It provides the electrical connections and communication pathways for the CPU, memory, storage devices, expansion cards, and other peripherals, enabling them to function together as a cohesive system.
- CPU Board (A) is incorrect because while the CPU is mounted on the motherboard, the motherboard encompasses much more than just the CPU.
- Memory Board (C) is incorrect; RAM modules are inserted into slots on the motherboard, but the motherboard itself is not solely dedicated to memory.
- Power Board (D) is incorrect; the power supply unit (PSU) provides power, and the motherboard distributes it, but it is not called a power board.
