Motherboards The Main Printed Circuit Board Inside The PC That Contains and Controls The Components That Are Responsible For Processing Data.
Motherboard is • Multi-layered printed circuit board • Copper circuit paths called traces carry signals and voltages across the motherboard • Some layers carry data for input/output while other layers carry voltage and ground returns
Think of a Motherboard as: • Futuristic City with many modular plug-in buildings, using power from a common electrical system • Multiple-lane highways of various widths transporting data between buildings • Data and power infrastructure for the entire computer
Motherboard • Holds The Processor • Memory • Expansion Slots • Connects Directly or Indirectly to Every Part of The PC
Motherboard Made Up Of: • A Chipset (known as the “glue logic”) • Some Code in ROM • Various Interconnections or Buses
Basic Input/Output System All motherboards include a small block of Read Only Memory (ROM) which is separate from the main system memory used for loading and running software. The ROM contains the PC’s BIOS.
CMOS RAM Motherboards include a separate block of memory made for low power consumption CMOS RAM chips, which is kept alive by a battery even when the PC’s power is off.
CPU type and speed Chipset Secondary cache type Types of slots Number of slots Type of memory Number of memory sockets and maximum memory Type of case ROM Plug & Play compatibility Type of keyboard Motherboard Determines:
Form Factors • Form factor means the size and shape of the actual motherboard • 3 most common Form Factor classifications: • Baby AT • ATX • Slimline NLX
Deal with reputable manufacturer Ensure that it has same form factor as current case Check the power supply requirements and AMD processors Verify the form factor of your computer case matches the form factor of any motherboard you plan to buy Avoid tweaking voltages and timings Advice on Buying Motherboards
