During a server installation, which component is responsible for communication between the CPU and memory?

The correct choice is the motherboard, as it serves as the main printed circuit board (PCB) in a computer that connects the CPU (central processing unit) to various components, including the memory modules (RAM). The motherboard encompasses the chipset that controls the communication pathways, allowing the CPU to retrieve and store data to and from the memory. This interaction is crucial for the overall performance and efficiency of the system during operation.

The power supply provides electricity to the entire system but does not facilitate direct communication between the CPU and memory. The hard drive is a storage device responsible for data storage rather than the processing of that data. The GPU (graphics processing unit) primarily handles rendering graphics and image processing but does not have a direct role in the communication link between the CPU and the system memory.
