Week Two

This week we looked at how the internet was invented and also how some of the technical jargon works.

Before this weeks lecture I went and did the topic 1.1 and the activities involved.

Heres what I learned about how the net works;

The net works like a pizza delivery, the hungry drunk guy (client) calls up the angry, underpaid, pimply teen (server) asking for a certain pizza from that shop (the shop being the website and the certain pizza being a particular page).

The teen then prepares the pizza ( server finds the right webpage), cuts it up and then boxes it (packet switching).

Then he jumps in his car and brings it to the hungry drunk guy (the page is sent to the client).

Of course it's a lot faster. And free.

Well it's a better metaphor than the one we had to watch;

I learnt what packet switching is; shrinking data to send online then sending through routers until it reaches the client. The data is then re-organized on the other side in the correct order.

And IP's; The computers address, anything connected to the net has one. Version 4 of these was introduced in 1977. However these are usually found by connecting an IP with a...

Domain name (DNS); A name or words mapped to an IP address (easier to understand and remember when typing). I believe they were introduced in 1984.

We also learnt some historical facts about the creation of the net which was quite interesting.

Also, apparently the web is not the same as the internet. The terms mean different things.
(Update) Oh! Yes, the internet is a series of networked computers while the web is an application that makes use of it!

And that was the second week.
