Do you know what happened?
There has been a cyberattack.
And I have a mission.
I need to save the world from hackers.
But with this old computer
it's just not possible.
Bur do you know exactly what a computer is?
Well, it's a machine that is used for a lot of things,
like browsing the Internet,
studying, working, researching,
watching movies or playing videogames.
You can write texts, draw, do maths
or even make videocalls.
This is the screen,
where we can see all the images and the data.
Do you know what this is?
Yes, it's a mouse!
With the mouse, we can give orders to the computer
by moving the arrow on the screen and clicking where we want.
This is the keyboard.
Look how many keys it has.
Each key has a letter and number or a symbol.
And do you know what this is?
That right, it's a speaker.
The speakers reproduce sounds when we listen to music
or watching a movie.
Perhaps, instead of speakers you use this.
Do you know what they're called?
Of course, this are headphones o airphones.
And we can listen to music.
Very useful if you don't want to disturb other people.
Lots of headphones have a built-in microphone,
so we can use them when we make videocalls.
And something else from videocalls.
What's this?
It's a web camera or webcam.
We use it for videocalls so we can see each other.
And this is my printer.
We use it to transfer text
or images to paper.
And of course, very important,
all these things need to be connected
to the computer using wires.
So my computer was so old
and so slow
I decided to buy something new.
Do you know what this is called?
Exactly, it's a laptop.
My new laptop.
And this is amazing,
because it has everything we've see built into it,
It's all in one.
We have the keyboard here,
the mouse here,
here's the screen
here's the webcam.
It also has speakers and a microphone.
And best of all,
it connects everything with wi-fi.
So I don't need any wires.
Do you know what wi-fi is?
It means "wireless connection".
So I can connect to the Internet, to the printer,
to anything through the wi-fi.
Now I've started up my new laptop.
It's so fast it's perfect for my mission
to save the world from the cyberattack!
Let's go.
See you next time, everybody. Bye!
