We're going to show you what these parts are and what they're used for, starting what they standard desktop model.

The computer case holds the main components of the computer.

This is where the actual processing happens today.

Most cases air what we call tower cases, which means they stand up vertically.

But they can also come another 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 L, C, D or L E D 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, Thio 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 Elektronik guy.

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 touch pad.

The touch pad 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 set up.

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.
