FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Video capability is sometimes integrated into the Northbridge. Southbridge-Allows the CPU to communicate with slower speed devices including hard drives, Universal Serial Bus (USB) ports, and expansion slots.

Detailed explanation-2: -Southbridge is a reference to a chipset on a PC motherboard. It is a group of microchips designed for a single function and manufactured as a single unit. This chipset controls or manages input and output (I/O). Examples of I/O interface connections controlled by southbridge are USB, serial, IDE and ISA.

Detailed explanation-3: -A northbridge is connected directly to a CPU via the front-side bus (FSB) to handle high-performance tasks, and is usually used in conjunction with a slower southbridge to manage communication between the CPU and other parts of the motherboard.

Detailed explanation-4: -The term chipset often refers to a specific pair of chips on the motherboard: the northbridge and the southbridge. The northbridge links the CPU to very high-speed devices, especially RAM and graphics controllers, and the southbridge connects to lower-speed peripheral buses (such as PCI or ISA).

Detailed explanation-5: -A control bus is a computer bus that is used by the CPU to communicate with devices that are contained within the computer. This occurs through physical connections such as cables or printed circuits.
