there are many different types of
computers
but they all use similar parts to
operate
in this video we're going to show you
what these parts
are and what they're used for starting
with
a standard desktop model
the computer case holds the main
components of the computer
this is where the actual processing
happens
today most cases are what we call tower
cases
which means they stand up vertically but
they can also come in other
shapes and sizes to view things on your
computer
you'll need a monitor the monitor uses
the video processor
inside your computer case to display
images text and other content
most monitors have an lcd or led
display both of which are very thin
so they don't take up much space
all-in-one models are even more compact
since they combine the monitor
and the computer case into a single unit
to interact with your computer you'll
need a keyboard
and a mouse keyboards come in many
different styles
including wireless and ergonomic
the mouse is used to control the mouse
pointer on the screen
so you can click and interact with your
computer
most mice detect movement using an
optical sensor on the bottom
underneath you'll find a small
electronic eye
laptops combine all of these things into
one
that includes the components that are
normally inside the computer case
plus a built-in screen
keyboard and touchpad
the touchpad is a small touch sensitive
area
that takes the place of a traditional
mouse
it lets you control the mouse pointer
using a drawing motion with your finger
laptops offer the best of both worlds
when it comes to portability
you can use them on the go thanks to the
built-in battery
or you can connect a separate monitor
keyboard and mouse effectively turning
your laptop
into a desktop so those are the basic
parts of any computer setup
as you can see each part plays an
important role
which you'll come to understand as you
spend more and more time
with your computer
