There are many different types of computers, but they all use similar parts to operate.

2
00:00:06,639 --> 00:00:12,080
In this video, we're going to show you what these parts are and what they're used for,

3
00:00:12,880 --> 00:00:15,919
starting with a standard desktop model.

4
00:00:17,039 --> 00:00:20,239
The computer case holds the main components of the computer.

5
00:00:20,960 --> 00:00:23,920
This is where the actual processing happens.

6
00:00:24,719 --> 00:00:29,120
Today, most cases are what we call tower cases,

7
00:00:29,120 --> 00:00:34,960
which means they stand up vertically, but they can also come in other shapes and sizes.

8
00:00:35,759 --> 00:00:43,039
To view things on your computer, you'll need a monitor. The monitor uses the video processor

9
00:00:43,039 --> 00:00:49,119
inside your computer case to display images, text, and other content.

10
00:00:49,920 --> 00:00:58,399
Most monitors have an LCD or LED display, both of which are very thin so they don't take up much

11
00:00:58,399 --> 00:01:05,280
space. All-in-one models are even more compact since they combine the monitor

12
00:01:05,280 --> 00:01:11,599
and the computer case into a single unit. To interact with your computer you'll

13
00:01:11,599 --> 00:01:17,659
need a keyboard and a mouse. Keyboards come in many different styles including

14
00:01:17,659 --> 00:01:23,780
wireless and ergonomic. The mouse is used to control the mouse pointer on this

15
00:01:23,780 --> 00:01:30,799
screen so you can click and interact with your computer. Most mice detect

16
00:01:30,799 --> 00:01:36,680
movement using an optical sensor on the bottom. Underneath you'll find a small

17
00:01:36,680 --> 00:01:44,159
electronic eye. Laptops combine all of these things into one that includes the

18
00:01:44,159 --> 00:01:50,859
components that are normally inside the computer case plus a built-in screen,

19
00:01:50,859 --> 00:01:58,359
keyboard, and touchpad. The touchpad is a small touch-sensitive area that takes

20
00:01:58,359 --> 00:02:04,099
the place of a traditional mouse. It lets you control the mouse pointer using a

21
00:02:04,099 --> 00:02:09,960
drawing motion with your finger. Laptops offer the best of both worlds when it

22
00:02:09,960 --> 00:02:17,460
comes to portability. You can use them on the go thanks to the built-in battery or

23
00:02:17,460 --> 00:02:22,759
Or you can connect a separate monitor, keyboard, and mouse,

24
00:02:23,379 --> 00:02:26,460
effectively turning your laptop into a desktop.

25
00:02:27,379 --> 00:02:30,599
So those are the basic parts of any computer setup.

26
00:02:31,120 --> 00:02:34,740
As you can see, each part plays an important role,

27
00:02:34,900 --> 00:02:40,180
which you'll come to understand as you spend more and more time with your computer.
