What is the Internet?
If a 5-year-old asked you "What is the Internet?"
how would you answer?
Internet Brainstorm
What do we use the Internet for?
How do we access the Internet?
Who pays for the Internet, and who gets paid?
The Internet
vs
The World Wide Web
What's the difference?
The Internet
A global system of interconnected computer networks.
The Internet is a network
of computer networks.

Who owns it all?
Who owns the Internet?
And who owns the Web?
Who owns the Internet?
Who owns the World Wide Web?
A web page is made of three main languages
HTML is the markup language
CSS is the style sheet language
JavaScript is the programming language
HTML + CSS + JS = Website!
Loading a Webpage
Kinda like telephones!
The Internet can be compared to the telephone system:
- Nobody owns the whole thing
- Companies do control individual parts
- Telephone numbers and IP addresses are unique
- There is no central control room
An ISP can charge extra to allow access
to your favourite website
e.g. Facebook, YouTube, Google
A government can censor access to information
e.g. North Korea and China
Chorus owns the Southern Cross Cable
They could slow down international requests for other ISPs
Your corner of the web
By creating your own website, you are taking ownership of a small portion of the world wide web.
It's all yours.
You can publish and share anything you like, go forth and create!
