So, what exactly is the Internet?
If your friend's younger sister asked you to describe the Internet, how would you explain it to her? Before we go any further in this course, let's take a few minutes to look at this online world we're immersed in.
First, on your own or with a group of friends, create a visual representation of what you think the Internet is and how it works. You could try using a new digital creation tool such as
easel.ly or you could grab a napkin and a pen. Just try to lay it out visually.
Then, watch the two videos below to compare your design to what is presented in the clips.

The World Science Festival created this short video explainer on how the Internet works.
VIDEO #2: Andrew Blum
When a squirrel chewed through a cable and knocked him offline, journalist
Andrew Blum started wondering what the Internet was really made of. So he set out to go see it -- the underwater cables, secret switches, and other physical bits that make up the net.
After you have watched Andrew Blum's video, go to the
Ted Talk website to read over the comments. Don't be shy - jump in with your own perspective. You have much to offer, so add your thoughtful comments to the discussion and see who responds.
