Answer:
Northbridge
Step-by-step explanation:
A computer chipset is a group of circuits that coordinates and controls the data flow between components of a computer. These components involve CPU, main memory, cache memory, and devices located on the buses. A computer has 2 main chipsets: Northbridge and Southbridge
A northbridge or host bridge is one of the two chip sets on an Advanced Technology extended motherboard. It is also called memory controller. It controls communication between processor (CPU) and RAM. This is the reason of Northbridge being connected directly to the CPU. Northbridge chip set is in charge for tasks that demand the highest performance.
It is also called Graphics and Memory Controller Hub . It is responsible for communication between CPU, RAM and Graphics Card. Southbridge also connects to Northbrige. It also acts as a mediator which helps southbridge chip to communicate with the CPU, graphics controller and RAM. Northbridge is connected to the CPU by the front-side bus (FSB).
