Music

00:10.000 --> 00:13.000
Basic parts of a computer.

00:13.000 --> 00:16.000
There are many different types of computers,

00:16.000 --> 00:19.000
but they all use similar parts to operate.

00:19.000 --> 00:24.000
In this video, we're going to show you what these parts are

00:24.000 --> 00:26.000
and what they're used for.

00:26.000 --> 00:30.000
Starting with a standard desktop model,

00:30.000 --> 00:35.000
the computer case holds the main components of the computer.

00:35.000 --> 00:38.000
This is where the actual processing happens.

00:38.000 --> 00:42.000
Today, most cases are what we call tower cases,

00:42.000 --> 00:45.000
which means they stand up vertically.

00:45.000 --> 00:49.000
But they can also come in other shapes and sizes.

00:49.000 --> 00:52.000
To view things on your computer,

00:52.000 --> 00:54.000
you'll need a monitor.

00:54.000 --> 00:57.000
The monitor uses the video processor

00:57.000 --> 01:00.000
to display images,

01:00.000 --> 01:03.000
text and other content.

01:03.000 --> 01:07.000
Most monitors have an LCD, LED display,

01:07.000 --> 01:09.000
both of which are very thin,

01:09.000 --> 01:12.000
so they don't take up much space.

01:12.000 --> 01:16.000
All in one model are even more compact.

01:16.000 --> 01:20.000
Since they combine the monitor and the computer case

01:20.000 --> 01:22.000
into a single unit,

01:22.000 --> 01:24.000
to interact with your computer,

01:24.000 --> 01:27.000
you'll need a keyboard and a mouse.

01:27.000 --> 01:30.000
Keyboards come in many different styles.

01:30.000 --> 01:33.000
Including wireless and ergonomic,

01:33.000 --> 01:37.000
the mouse is used to control the mouse pointer on the screen.

01:37.000 --> 01:41.000
So you can click and interact with your computer.

01:41.000 --> 01:44.000
Most mice detect movement,

01:44.000 --> 01:47.000
using an optical sensor on the bottom.

01:47.000 --> 01:51.000
Underneath, you'll find a small electronic guy.

01:51.000 --> 01:55.000
Laptops combine all of these things into one.

01:55.000 --> 01:57.000
That includes the components

01:57.000 --> 02:00.000
that are normally inside the computer case.

02:00.000 --> 02:03.000
Plus, a built-in screen.

02:03.000 --> 02:05.000
Keyboard and touchpad.

02:05.000 --> 02:09.000
The touchpad is a small touch-sensitive area.

02:09.000 --> 02:12.000
That takes the place of a traditional mouse.

02:12.000 --> 02:15.000
It lets you control the mouse pointer.

02:15.000 --> 02:18.000
Using a dry motion with your finger,

02:18.000 --> 02:20.000
laptop software the best of both worlds

02:20.000 --> 02:22.000
when it comes to portability.

02:22.000 --> 02:24.000
You can use them on the go.

02:24.000 --> 02:26.000
Thanks to the built-in battery,

02:26.000 --> 02:30.000
or you can connect a separate monitor,

02:30.000 --> 02:32.000
keyboard and mouse.

02:32.000 --> 02:35.000
Effectively turning your laptop.

02:35.000 --> 02:37.000
Into a desktop,

02:37.000 --> 02:41.000
so those are the basic parts of any computer setup.

02:41.000 --> 02:43.000
As you can see,

02:43.000 --> 02:46.000
each part plays an important role.

02:46.000 --> 02:48.000
Which you'll come to understand

02:48.000 --> 02:52.000
as you spend more and more time with your computer.
