Answer: A - The Northbridge is responsible for the connection between the processor and high-speed devices, such as a PCI Express video card.

Key Takeaway: Older Intel and current AMD motherboards contain two chips within the chipset, the Northbridge and Southbridge. The Northbridge is responsible for the connection between high-speed devices, such as PCI Express Video Cards and RAM, and the Southbridge is responsible for secondary controllers, such as USB and FireWire. The CMOS stores system settings reported by the BIOS, and the Front Side Bus (FSB) connects the Northbridge to the CPU.
