Computer
A computer consists of many components, all very different in functionality but
they all work together to make a powerful machine that helps us in our everyday activities.
They facilitate basic functions such as term paper or speeches or even managing our
money on a day-to-day basis. Of course there are some computers that are very powerful
and run software that enables government agencies such as NASA precisely project all of
the events in our solar system. What I would like to do today is to demonstrate all the
components that make up the basic computer system, not necessarily the one that is used
by the government.
The component that we use to hold the entire computer modules together is called
a computer case. There are a couple of different types of computer cases. One type is
called AT case which is used for the older computers, and the second one is called ATX
case which is used for more resent computers. Cases may also come in different sizes,
colors and styles. The main different between the two cases is the power supply that
come with them. A power supply, simply put, is the part that gives electricity to the
computer.
