Well, now it's time to learn a litte bit more about our useful technology. Here we have seven basic hardware components of our computers. Let's see them!
-COMPUTER CASE
A computer case is the enclosure that contains most of the components of a computer, excluding the monitor, keyboard, mouse, speakers, etc.You can find the power button on it. This part is like the "computer brain".

-MONITOR / COMPUTER SCREEN
The monitor shows us all the information directly from the computer. It's like a television. Before the monitors were thicker, but nowadays they are slimmer and with higher and better resolution.

-MOUSE
The mouse is the principal device because we handle the computer which it. Moving the mouse we move an arrow that can be placed in any place of the screen. The mouse has a left button to select things, a right button to show some secondary action and a wheel in the center to move up and down inside the programs.

-KEYBOARD
Do you remember the old typewriter machines? Well, today the keyboard has replaced them!. With it we can write words in text windows or in writing programmes (like Microsoft Word), and we can handle some functions of the PC by pressing some buttons on it.

-PRINTER
This machine allows us to print our documents directly from the computer. The printer needs blank folios and ink cartridges to work. We can print photos, pictures, works, texts, etc.

-SPEAKERS
With the speakers we can hear all the sounds that appear on our computer. We need them to listen to our favorite songs, to watch a movie or, for example, to hear how to pronounce a word correctly in English.

-WEBCAM
The webcam is a very curious device. With it we can keep a live conversation with a friend or family member (even if they're in any part of the World) because this cam is recording our faces and it's sending that record through Internet. This process is known as a video call, and it is now possible (some people think that video call is an invention from science-fiction films!)
