What does the motherboard in a computing system house?

The motherboard is a crucial component of a computing system, serving as the main printed circuit board that connects all other components to one another. It houses the CPU (Central Processing Unit), which is the primary processor responsible for executing instructions and processing data. Additionally, the motherboard contains RAM (Random Access Memory) chips that provide temporary storage for data being used and processed by the CPU, enabling faster access compared to other storage types like hard drives.

Moreover, the motherboard integrates various electronic circuit elements that facilitate communication between the CPU, RAM, and other peripheral devices, including input/output (I/O) interfaces and expansion slots. This integration allows seamless operation and coordination of the entire system. In sum, the specific components that the motherboard houses—such as the CPU, RAM, and necessary circuitry—are integral to the functionality of the computer, making this choice the correct answer.
