Motherboard
Overview
It is a Printed Circuit Board that performs the key functions to enable smooth running of the computer.
Lesson Covered in this Module
Motherboards
Standard Expansion Buses
Introduction
Motherboard is a Printed Circuit Board which possesses different components for various purposes. It contains
CPU
BIOS,
Memory
I/O ports
External I/O connectors
I/O controllers
Expansion slots
Chipsets.
AT and Baby AT
To overcome the problem created by AT Form factor, the Baby AT form factor was introduced.
Baby AT is designed to hold the peripheral devices like keyboard, video and mouse.
It could not accommodate the combination of processor, heat sink and fan. Cooling
Motherboard Components
Chipset and Functions
Different chips integrated to a single chip called the chipset.
North bridge and South bridge was introduced to the motherboard with PCI slots.
The south bridge controls the slower I/O components like the Serial ports, USB ports and the IDE.
The new technology, Intel Hub Architecture (IHA) uses two chips called hub controllers.
The hub controllers are
Graphics and Memory Controller Hub (GMCH)
I/O Controller Hub (ICH)
The chipset determine
The voltage provided to the processor
Number of processors that can be supported
The speed of the processor
The different memory modules that are supported
Bus speed
The different expansion bus that are supported
Power Management
