Which component enables the CPU to communicate with I/O devices and storage, managing PCIe lanes?

• A. Chipset
• B. Chassis
• C. Heatsink
• D. TIM

Answer: (A)

The component that lets the CPU talk to I/O devices and storage and coordinates the PCIe lanes is the chipset. It serves as the bridge between the processor and peripheral controllers, housing the PCIe root complex and other I/O controllers (USB, SATA, NIC, etc.). The chipset receives requests from the CPU, routes them over the PCIe lanes to the appropriate device, and handles coordination, timing, and protocol tasks to move data efficiently. In many systems the chipset expands the available PCIe and I/O interfaces beyond what the CPU provides directly, enabling communication with a wide range of storage and peripheral devices. The other options don’t play this role: the chassis is just the case, the heatsink dissipates heat, and TIM is the thermal material between the CPU and cooler.
