0:15:04 > 0:15:06Welcome to Science Fiction,
0:15:06 > 0:15:08where we explore the vast web of science...
0:15:08 > 0:15:11..and try to untangle the fact from the fiction.
0:15:11 > 0:15:14BUD-E, what's today's question, please?
0:15:14 > 0:15:16How are you, love? I've just been in for a service, there.
0:15:16 > 0:15:18Feeling chipper, so I am.
0:15:18 > 0:15:21Today's question comes from Eden in Kilmeaden.
0:15:21 > 0:15:24Where exactly is the Internet? Is it up in the sky?
0:15:24 > 0:15:27Hang on there a minute, I'll ask the Internet. Its knows everything.
0:15:27 > 0:15:29WINDOWS ERROR NOISE
0:15:29 > 0:15:31What's the password on this, again?
0:15:31 > 0:15:32The Internet is a vast network
0:15:32 > 0:15:36allowing people all over the world to exchange information.
0:15:36 > 0:15:38It's sort of like a world-wide web. Ha!
0:15:38 > 0:15:41To help us understand how the Internet works,
0:15:41 > 0:15:43let's imagine a really big road network.
0:15:45 > 0:15:46Ha! I'm in! Right.
0:15:46 > 0:15:49The cables, wireless networks and satellites
0:15:49 > 0:15:52are like the motorways, roads and bike lanes.
0:15:53 > 0:15:58You could say really it's like an information superhighway. Ha ha!
0:15:58 > 0:16:00Over this physical network,
0:16:00 > 0:16:01information travels in all directions
0:16:01 > 0:16:04and in many different forms.
0:16:06 > 0:16:08There's just so much to learn.
0:16:08 > 0:16:10Look here, there's a cat playing banjo!
0:16:12 > 0:16:15So, now you know, Eden, the Internet is all around us,
0:16:15 > 0:16:18not just fixed at one point in the sky.
0:16:18 > 0:16:20So that's just a load of old science fiction.
