where we explore the vast web of science... | 0:15:06 | 0:15:08 | |

Today's question comes from Eden in Kilmeaden. | 0:15:18 | 0:15:21 | |

The Internet is a vast network | 0:15:31 | 0:15:32 | |
allowing people all over the world to exchange information. | 0:15:32 | 0:15:36 | |
It's sort of like a world-wide web. Ha! | 0:15:36 | 0:15:38 | |
To help us understand how the Internet works, | 0:15:38 | 0:15:41 | |
let's imagine a really big road network. | 0:15:41 | 0:15:43 | |
Ha! I'm in! Right. | 0:15:45 | 0:15:46 | |
The cables, wireless networks and satellites | 0:15:46 | 0:15:49 | |
are like the motorways, roads and bike lanes. | 0:15:49 | 0:15:52 | |
You could say really it's like an information superhighway. Ha ha! | 0:15:53 | 0:15:58 | |
Over this physical network, | 0:15:58 | 0:16:00 | |
information travels in all directions | 0:16:00 | 0:16:01 | |
and in many different forms. | 0:16:01 | 0:16:04 | |
There's just so much to learn. | 0:16:06 | 0:16:08 | |
Look here, there's a cat playing banjo! | 0:16:08 | 0:16:10 | |
