What is the primary function of a motherboard?

The primary function of a motherboard is to connect and allow communication between all computer components. The motherboard serves as the central hub of a computer system where various hardware components, such as the CPU, RAM, storage, and peripheral devices, can communicate with one another. It contains the necessary circuits and connectors that enable data transfer and power distribution among these components, allowing them to work together seamlessly. This connectivity ensures that the entire system operates efficiently, with components exchanging information as needed, which is fundamental for the system’s overall functionality.

Other aspects of the computer, such as power supply or cooling, while important, are not the main role of the motherboard. Instead, those functions support the motherboard's role in facilitating communication between components.
