Question

which of the following best describes the purpose of the north - bridge chipset?
the chip that controls all of the usb ports.
the chip that controls the system bios.
the chip that controls the pci bus.
the chip that controls the audio.

Explanation:

The north - bridge chip is mainly responsible for managing high - speed communication between the CPU, memory, and other high - speed components. The chip that controls the system BIOS is related to the north - bridge in terms of its connection to the CPU and memory for initial system setup. The chip that controls all USB ports is usually part of the south - bridge which handles lower - speed I/O. The chip that controls the PCI bus can be part of the south - bridge or have its own controller in some cases. The chip that controls the audio is also often part of the south - bridge or a separate audio codec. The system BIOS chip has a closer connection to the north - bridge's function of high - level system control.

Answer:

The chip that controls the system BIOS.
