1.2.2.1 Connection: Chipset

As discussed earlier, the chipset of a computer can include I/O peripherals. The northbridge of a chipset, for example, often includes an integral video controller. This is because a video controller (otherwise known as the ``graphics card'') requires a high speed connection to the processor.

The southbridge, on the other hand, may include an integral sound controller, an Ethernet controller and other low speed I/O controller.

When I/O peripherals are integrated into the chipset, the cost of a PC is lowered. At the same time, it is easier to assemble and test a PC. Most chipset-included peripherals can be disabled. This allows the owner of a PC to install custom I/O peripherals.
