FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The southbridge chipset controls the rest of the components connected to the computer, including communication between the processor and expansion ports such as USB ports and sound cards.

Detailed explanation-2: -A southbridge chipset handled many of a computer’s I/O functions, such as USB, audio, the system BIOS, the ISA bus or the LPC bus, the low speed PCI/PCIe bus, the IOAPIC interrupt controller, the SATA storage, the historical PATA storage, and the NVMe storage.

Detailed explanation-3: -For PC motherboards, there are two main chipsets: the northbridge and the southbridge. The northbridge is directly connected to the CPU, allowing for faster transmissions between it and ports that require faster speeds. These include your RAM modules and PCI express cards, as well as AGP.

Detailed explanation-4: -Starting with Intel’s 8xx chipsets, Northbridge and Southbridge were changed to Memory Controller and I/O Controller (see Intel Hub Architecture). Northbridge/Southbridge Chipset The Northbridge part of the chipset controls the high-speed channels, while the Southbridge controls the lower speed devices.

Detailed explanation-5: -The north bridge is a controller which controls the flow of data between the CPU and RAM, and to the AGP port.
