Final answer:
A motherboard is a system board component that provides a connection point for specialized cards or circuit boards.
Step-by-step explanation:
A motherboard, or system board, provides a connection point for specialized cards or circuit boards. One important component of a motherboard is the expansion slot, which allows users to add expansion cards to enhance the functionality and capabilities of the computer. These expansion cards can include graphics cards, sound cards, network interface cards, and more.
For example, if you want to improve the graphics performance of your computer for gaming or graphic design tasks, you can insert a dedicated graphics card into an available expansion slot on the motherboard. This graphics card will have its own specialized circuitry and memory to handle graphics processing, freeing up the system's main processor.
Overall, the motherboard serves as the central hub that connects all the different components of a computer system together, including the CPU, memory, storage devices, and peripherals. It ensures that these components can communicate with each other effectively and safely.
