South Bridge

35. A south bridge chipset handles controls all of the
computers I/O functions, such as USB, audio, serial, the
system BIOS, the ISA bus, the interrupt controller and
the IDE channels.
The north bridge typically handles communications
among the CPU, in some cases RAM, and PCI Express
(or AGP) video cards.
CMOS is short for Complementary Metal-Oxide
Semiconductor. CMOS is an on-board semiconductor
chip powered by a CMOS battery inside computers that
stores information such as the system time and date and
the system hardware settings for your computer.

specialized networking, audio, and telephony equipment.
Peripheral Component Interconnect,[1] part of the
PCI Local Bus standard and often shortened to
PCI) is a computer bus for attaching
hardware devices in a computer.
