History of Technology 6: Introduction to the Internet

What's the difference between the internet and the world wide web? How do computers talk to each other? Couldn't we just Google these questions? Why do we ask so many questions? What if the hokey-pokey really is what it's all about?

If somebody told them our internet powers came from a magic turtle orbiting the Earth… [Turtle beaming down the internet]

00:26

…they’d shrug and say "weird, but sure…"

00:28

Then they’d go back to Tweeting their every minor thought and buying crocheted dog sweaters [Dogs running around with sweaters on]

00:33

from Lithuania on Etsy.

00:34

The basic idea behind the internet started with people trying to find a way for computers [Computer screen talking]

00:39

to talk to one another.

00:40

Which kinda sounds like scientists wanted those lonely computers to share their feelings [A computer walks away from another computer]

00:44

with each other, but that’s not exactly what we mean.

00:47

Also, when computers start having feelings and sharing those feeling with each other, [Computer looks angry]

00:51

the next stop is the robot apocalypse…

00:53

So…yeah…best to avoid that. [Computer shoots people with laser beams]

00:55

It’s probably most accurate to say that the internet is a global network that allows

00:59

different computers to share information.

01:01

There…that definition sounds pretty official, right? [Computers linked]

01:04

So if we link a few computers together, we get a network… [Computers all connected together]

01:08

But we don’t exactly have the internet yet.

01:10

Still, the early experiments that created the first computer networks are what eventually [Computer network expanding]

01:14

led to the big guy.

01:16

So what did it take to create something worthy of being called the Internet?

01:19

Well, they had to interconnect smaller networks all over world to make one giant global net. [Different networks are connected together]

01:25

Kinda makes us think that we’ve all been caught by a cosmic poacher who’s come to [Planet Earth stuck in a net]

01:29

claim our hides…

01:30

But fortunately, that's not the case.

01:33

So what exactly are we using to create the massive, worldwide network?

01:37

Wires.

01:38

Fiber optic ones, copper ones, but mostly…wires. [Wires going all over the world]

01:41

And, of course, we can connect wirelessly as well, with our cell phones, laptops, tablets, [Different wireless devices appear]

01:45

and whatever other new things they’ve come up with in the last 2 seconds.

01:49

How do we do this?

01:50

We bounce signals off of satellites that are orbiting the Earth. [Satellite sending signals back to the Earth]

01:54

Yeah, it's not actually a giant turtle.

01:56

Although that would be cool...

01:58

So that brings us to a pretty big question: what's the difference between the Internet [Question mark appears]

02:02

and the World Wide Web?

02:03

The internet is the actual global network that connects everything, but the World Wide

02:08

Web is what lets us access all that information.

02:11

Without the Web, all of the internet’s data would be a formless series of files and code. [Folders without names appear]

02:16

So the Web is sorta like a structure built on top of the internet that allows us to understand [The folders are organised by a net]

02:20

what we’re looking at.

02:21

World Wide Web also sorta makes it sound like the Earth is trapped in a giant spider’s [Planet Earth in a spider web]

02:25

web, but we’re not going to let it keep us up at night.

02:28

That’s what Melatonin is for. [Man falls to sleep]
