What is the main printed circuit board found in computers known as?

The main printed circuit board found in computers is referred to as the motherboard. This critical component serves as the backbone of the computer, connecting and allowing communication between various hardware parts, including the central processing unit (CPU), memory (RAM), storage devices, and peripheral components. The motherboard is essential for the overall function of a computer, as it provides the necessary circuitry for data transmission and power distribution.

In contrast, the power supply is responsible for converting electrical power from an outlet into usable power for the computer's components, while the graphics card is a specialized circuit board that handles rendering images, videos, and animations. The hard drive serves as the storage device where data is saved and retrieved. Each of these components has a specific role, but none replace the motherboard's fundamental function of linking all parts of the system.
