is a Motherboard?
A Motherboard (or System Board)
is a one of the most essential parts of not just
the computer, but many electronics such as televisions
and stereos. Also referred to as a Mobo, this
component is in charge of relaying information
between all the different components connected
to it. It's safe to say the microprocessor is
the heart of the computer and the motherboard
is the body and structure.
The system board itself is made
up of chips, transistors, and circuits. The different
components, such as the video card, pci cards, and the
memory modules talk to each other by transferring data
and information along the circuits, or buses on the
system board. Pretty much all the internal components
of a computer are connected to the system board.
Every motherboard operates off of a BIOS (Basic Input/Output
System), which is basically a small program inside a
chip on the board that controls how the motherboard
operates and handles the components connected to it.
When you first turn your computer on, before your operating
system loads up, you are seeing your BIOS in action.
All those gobbled up words running across the screen
is your BIOS running its self tests to see what all
is connected to the motherboard, and if there is any
problems with any of the components.
When building your own computer, making sure the motherboard
you choose has the correct socket for the processor
you choose is crucial. Most computer builders pick out
a processor first and then choose a motherboard accordingly.
So I you were to pick out a Socket 478 Pentium 4 processor
then you have to make sure you pick out a motherboard
that will fit a Socket 478 Pentuem 4 processor. It's
also always a good idea to purchase a motherboard with
more slots (pci and memory) than you currently need,
so you can have room for expansion.
My name is Sergio Woods and I've been studying computers
for over 7 years now. I have a great deal of knowledge
in aspects ranging from Internet Administration to software
programming to hardware and component installation.
In my studies I have come to realize that there are
very general things even the most casual computer user
should know how to do in order to keep their computer
running at its peak performance.
I feel the need to share my knowledge with any and everybody
who has the desire I do to learn everything there is
to know about the most revolutionary entity in our society.
I try my best to explain everything in layman's terms
without using a bunch of technical jargon. Also I've
realized that there are a lot of people charging people
an arm and a leg to give very common computer advise
which is not worth that much at all. Sometimes people
just need a little push in the right direction, and
Computer Maintain.com is here to give you that push.
