Final answer:
The Northbridge part of the chipset normally controls memory operations and graphics processing. It is a key component for handling high-speed tasks between the CPU, RAM, and sometimes the GPU.
Step-by-step explanation:
The two activities normally controlled by the Northbridge part of the chipset are:
- Memory operations
- Graphics processing
The Northbridge is a chip on the motherboard that handles communications between the CPU, memory, and occasionally the video graphics card. It plays a critical role in the performance of these components, especially in high-speed applications. The Northbridge has been traditionally responsible for dealing with high-speed tasks such as those involving the computer's RAM and the graphic's card's frame buffer, thus these two options (Memory operations and Graphics processing) are the correct choices. As technology advances, the role of the Northbridge has evolved, and in some modern computers, these functions are integrated into the CPU itself.
