What is the main purpose of a motherboard?

The primary role of a motherboard is to serve as the main circuit board that connects all the computer's components together. It provides a platform for the CPU, memory, storage devices, and peripheral cards to communicate with each other through buses and connectors. This interconnectedness allows different parts of the computer to work in unison, enabling the system to function as a cohesive unit.

While other functions, such as storing temporary data or powering components, may be associated with different parts of a computer system, the motherboard itself is fundamentally the hub that facilitates communication and data transfer among all elements. Each component relies on the motherboard to provide the necessary connections and pathways for signals, data, and power, thus establishing its critical role in computer architecture.
