00:00:04.540 --> 00:00:06.500
Do you know what happened?

00:00:06.540 --> 00:00:09.180
There has been a cyberattack.

00:00:09.220 --> 00:00:11.020
And I have a mission.

00:00:11.060 --> 00:00:14.100
I need to save
the world from hackers.

00:00:14.420 --> 00:00:16.260
But with this old computer

00:00:16.300 --> 00:00:18.300
it's just not possible.

00:00:20.420 --> 00:00:23.940
Bur do you know exactly
what a computer is?

00:00:24.180 --> 00:00:28.100
Well, it's a machine that is used
for a lot of things,

00:00:28.140 --> 00:00:30.060
like browsing the Internet,

00:00:30.100 --> 00:00:33.220
studying, working, researching,

00:00:33.260 --> 00:00:35.820
watching movies
or playing videogames.

00:00:36.260 --> 00:00:39.980
You can write texts, draw, do maths

00:00:40.020 --> 00:00:42.540
or even make videocalls.

00:00:44.420 --> 00:00:45.860
This is the screen,

00:00:45.900 --> 00:00:48.660
where we can see
all the images and the data.

00:00:48.700 --> 00:00:50.780
Do you know what this is?

00:00:55.420 --> 00:00:57.580
Yes, it's a mouse!

00:00:57.620 --> 00:01:00.980
With the mouse, we can give
orders to the computer

00:01:01.020 --> 00:01:04.860
by moving the arrow on the screen
and clicking where we want.

00:01:08.420 --> 00:01:10.220
This is the keyboard.

00:01:10.260 --> 00:01:12.060
Look how many keys it has.

00:01:12.100 --> 00:01:16.220
Each key has a letter
and number or a symbol.

00:01:16.860 --> 00:01:19.980
And do you know what this is?

00:01:24.980 --> 00:01:27.700
That right, it's a speaker.

00:01:27.740 --> 00:01:31.260
The speakers reproduce sounds
when we listen to music

00:01:31.300 --> 00:01:32.420
or watching a movie.

00:01:33.340 --> 00:01:37.340
Perhaps, instead of speakers
you use this.

00:01:37.380 --> 00:01:39.340
Do you know what they're called?

00:01:43.660 --> 00:01:47.300
Of course, this are
headphones o airphones.

00:01:47.340 --> 00:01:49.260
And we can listen to music.

00:01:49.300 --> 00:01:52.460
Very useful if you don't want
to disturb other people.

00:01:53.260 --> 00:01:56.780
Lots of headphones
have a built-in microphone,

00:01:56.820 --> 00:01:59.740
so we can use them
when we make videocalls.

00:02:00.020 --> 00:02:01.860
And something else from videocalls.

00:02:02.220 --> 00:02:03.460
What's this?

00:02:03.700 --> 00:02:06.300
It's a web camera or webcam.

00:02:06.340 --> 00:02:09.340
We use it for videocalls
so we can see each other.

00:02:09.380 --> 00:02:12.460
And this is my printer.

00:02:12.660 --> 00:02:15.100
We use it to transfer text

00:02:15.140 --> 00:02:16.900
or images to paper.

00:02:17.220 --> 00:02:19.460
And of course, very important,

00:02:19.500 --> 00:02:22.540
all these things need
to be connected

00:02:22.580 --> 00:02:25.500
to the computer using wires.

00:02:26.940 --> 00:02:29.900
So my computer was so old

00:02:29.940 --> 00:02:31.620
and so slow

00:02:31.660 --> 00:02:34.980
I decided to buy something new.

00:02:35.020 --> 00:02:37.420
Do you know what this is called?

00:02:42.740 --> 00:02:44.980
Exactly, it's a laptop.

00:02:45.020 --> 00:02:46.740
My new laptop.

00:02:47.060 --> 00:02:49.340
And this is amazing,

00:02:49.380 --> 00:02:53.540
because it has everything we've see
built into it,

00:02:53.580 --> 00:02:55.260
It's all in one.

00:02:55.420 --> 00:02:57.940
We have the keyboard here,

00:02:57.980 --> 00:02:59.540
the mouse here,

00:02:59.580 --> 00:03:01.380
here's the screen

00:03:01.420 --> 00:03:03.020
here's the webcam.

00:03:03.060 --> 00:03:06.820
It also has speakers
and a microphone.

00:03:06.860 --> 00:03:08.340
And best of all,

00:03:08.380 --> 00:03:12.860
it connects everything with wi-fi.

00:03:12.900 --> 00:03:15.620
So I don't need any wires.

00:03:15.660 --> 00:03:18.100
Do you know what wi-fi is?

00:03:18.140 --> 00:03:20.980
It means "wireless connection".

00:03:21.020 --> 00:03:24.220
So I can connect
to the Internet, to the printer,

00:03:24.260 --> 00:03:27.100
to anything through the wi-fi.

00:03:29.660 --> 00:03:32.180
Now I've started up my new laptop.

00:03:32.220 --> 00:03:36.940
It's so fast it's perfect
for my mission

00:03:36.980 --> 00:03:39.700
to save the world
from the cyberattack!

00:03:39.740 --> 00:03:40.780
Let's go.

00:03:41.980 --> 00:03:44.460
See you next time, everybody.
Bye!
