What are the two chips that make up the chipsets on motherboards?

The correct answer is based on the traditional architecture of motherboards, where the chipset consists of two primary components: the northbridge and the southbridge. The northbridge is responsible for handling high-speed connections, specifically between the CPU and memory, as well as communication with high-performance graphics cards. It plays a crucial role in ensuring optimal data transfer rates between these components.

The southbridge, on the other hand, manages lower-speed interfaces including USB ports, audio controllers, and the system's chipset for other peripherals. It serves as a communication hub that connects the CPU and memory to the various input/output devices and storage.

Together, these two chips form a cohesive system that enables effective communication throughout the motherboard, facilitating the smooth functioning of a computer. This distinction in roles and functions underscores why the correct answer identifies the northbridge and southbridge as the essential components of chipset architecture.
