What is the function of a motherboard in a computer?

• A. It powers the computer and manages thermal sensors.
• B. It stores the operating system on a boot drive.
• C. It connects and allows communication between the CPU, memory, storage, and expansion cards, forming the central backbone of the system.
• D. It provides an interface for display output only.

Answer: (C)

The main idea here is that the motherboard acts as the central hub that ties all the computer’s core parts together and lets them communicate. It provides the sockets and slots for the CPU, memory (RAM), and expansion cards, and it wires them up with buses and controllers so data can move where it’s needed. It also hosts interfaces for storage devices, USB, network, audio, and other peripherals, and it distributes power from the power supply to these components. This combination of connecting components, coordinating data flow, and housing essential controllers is what makes the motherboard the central backbone of the system. It isn’t responsible for powering the computer by itself—the power supply does that. It doesn’t store the operating system on its own—the OS sits on a boot drive. And while it may provide some video outputs, its primary role is not just display; it enables the CPU, memory, storage, and expansion cards to work together.
