How MotherBoard Work

A Motherboard is at the core of every computer system.
In desktop models it usually lines the floor of the system.
In tower and mini-tower models, it lies along one of the sides.
A motherboard’s components and features define a PC’s potential
and upgradepath. Virtually every essential computer part, data bus,
or electrical subsystem attaches to the motherboard in some way.
If the motherboard fails, the computer will not function.


You can identify a computer motherboard by the components that
attach to it and the layout of its parts. The most important motherboard
component is the microprocessor or CPU. Other significant components
include the number of memory slots onboard, the maximum amount of
memory the board supports, available PCI (Peripheral Component Interconnect) slots, the system bus or maze of wires connecting the
CPU to the PC’s numerous components, whether the board has
integrated audio or modem circuitry, and the range of speeds
supported by the processor.


As the motherboard works, data and timing signals transfer
from one connected component to another by way of interconnected
leads etched into the board. These leads are known as the system bus.
The power supply (which also connects to themotherboard) distributes
power to system components via the bus. The processor also
communicates with motherboard components by sending and
receiving instructions and data over the bus.

A motherboard is designed to take advantage of particular technology.
For example, certain processors function correctly only when
installed on particular motherboards and chipsets.
You won’t be able to take advantage of new technology
(a speedier processor or different type of graphics, for example)

if the board installed in your computer lacks the appropriate circuitry.
