The name is derived from drawing the architecture in the fashion of a map. The CPU would be at the top of the map at due north. The CPU would be connected to the chipset via a fast bridge (the [[Northbridge (computing)|northbridge]]) located ''north'' of other system devices as drawn. The northbridge would then be connected to the rest of the chipset via a slow bridge (the southbridge) located ''south'' of other system devices as drawn.

The LPC Bridge provides a data and control path to the SIO (the normal attachment for the keyboard, mouse, parallel port, serial port, [[Infra-red|IR port]], and floppy controller) and [[BIOS]] ROM ([[Flash memory|flash]]).
*[[System Management Bus|SMBus]]. The SMBus is used to communicate with other devices on the motherboard (e.g. system fans).
*[[Direct memory access|DMA controller]]. The DMA controller allows ISA or LPC devices direct access to [[main memory]] without needing help from the CPU.
