Motherboards
z The Main Printed Circuit Board Inside The PC That Contains and Controls The Components That Are Responsible For Processing Data.
Motherboard is
z Multi-layered printed circuit board
z Copper circuit paths called traces carry signals and voltages across the motherboard
z Some layers carry data for input/output while other layers carry voltage and ground returns
Think of a Motherboard as:
z Futuristic City with many modular plug-in buildings, using power from a common electrical system
z Multiple-lane highways of various widths transporting data between buildings
z Data and power infrastructure for the entire computer
Motherboard
z Holds The Processor

z Form factor means the size and shape of the actual motherboard
3 most common Form Factor classifications:
y Baby AT
y ATX
y Slimline NLX
Advice on Buying Motherboards
z Deal with reputable manufacturer
z Ensure that it has same form factor as current case
z Check the power supply requirements and AMD processors
z Verify the form factor of your computer case matches the form factor of any motherboard you plan to buy
z Avoid tweaking voltages and timings
