Motherboard of a pc
1.
2. Introduction:
A motherboard is the central or primary printed
circuit board making up a complex electronic
system,such as a modern computers.
It is also known as a main board, base board, system
board, and planar board.
A motherboard, is like a backplane,provides the
electrical connections by which other components of
the system communicate.
3. History of the MotherBoard:
Before the invention of microprocessors, computers were built in
mainframes, with components which were connected by a backplane that
had countless slots for connecting wires.
In old designs, wires were needed to connect card connector pins but, soon
they became a thing of past with the invent of PCBs.
The CPU, memory and other peripherals were all housed on this printed
circuit board.
During the late 1980s and 1990s, it was found that increasing the number of
peripheral functions on the PCB was very economical.
Hence, single Integrated Circuits (ICs), capable of supporting low-speed
peripherals like serial ports , mouse, keyboards, etc., were included on the
motherboards.
4. History of the MotherBoard:
By the late 1990s, they began to have full range of audio,
video, storage and networking functions on them. Higher
end systems for 3D gaming and graphic cards were also
include later.
Micronics, Mylex, AMI, DTK, Orchid Technology,
Elitegroup, etc. were few companies that were early
pioneers in the field of motherboard manufacturing but,
companies like Apple and IBM soon took over.
They offered high end, sophisticated motherboards that
included upgraded features and superior performance
over prevailing motherboards.
5. Functions:
The Motherboard takes care of the entire system one way or
the another.
The function of the computer motherboard is to act as the
main circuit board that connects and communicates to all the
devices and components attached.
The motherboard also facilitates the communication of
devices with each other.
Measuring the motherboard's speed can be difficult and
varies, depending on the CPU attached.
A motherboard has a maximum front side bus (FSB) speed,
for example, but a CPU with that speed as well must be used.
6. Functions:
BIOS or basic input output and Boot memory also resides on the
motherboard.
BIO is a kind of software which works when we turn on the
computer.
BIO is also called a lower level program because it is installed in
the hardware.
The job of the BIOS is to act as a communication channel between
motherboard and softwares.
It is this printed circuit which contains chips and many expansion
cards to facilitate your working.
It does not matter which ever component you attach to your
motherboard, the basic functioning of that device is dependent
upon on the main board.
7. Other features and Functions
of Main Board
Mother board also contains a chip set. This chip set is really
essential as it monitors the data flow in your personal
computer.
It guides the movement and flow of data through the buses.
Motherboard chipset guides the data towards the correct
paths and ultimately correct destinations.
Therefore it is mother board where you plug in your video
cards, memory, cache and cards.
Motherboards are not produced in only one shape and
size. The shape and the size of the mother board is adjusted
depending on the need of the manufacturers.
12. Troubleshooting:
Motherboards fail for a variety of
reasons,including dust,
manufacturing defects,
electrostatic discharges and
flexing.
There are three types of
motherboard failure,
Catastrophic,
Component
Ethernal
13. Troubleshooting:
If the pc will not boot, it is catastrophic failure.This often
occurs within the first 30 days a motherboard is in use.
Component failure may occur as an intermittent
problem or a flaky connection between a device and the
motherboard. The most common causes of component
failure are electrical surges.
Ethereal symptoms are the most difficult ones to
diagnose. You may get intermittent problems or the
computer may reboot or you may get a blue screen of
death.
