A short explanation of what makes the World Wide Web work: browsers, packets, servers addresses and links.
First, a quick message from Common Craft.

Have you ever wondered, when you visit a website, where those words and images come from?
00:00:14
This is the World Wide Web in plain English.
00:00:20
These days, as long as we have an internet connection, using the web is pretty easy.
00:00:25
We can visit billions of pages on things from pet alligators to the weather in Holland.
00:00:30
To help figure out how it works, let's pretend we can get really small,
00:00:36
follow the wires, and explore what makes the web work.
00:00:40
In order to get to the web, we need a connection from our home or business to the rest of the online world.
00:00:44
This usually happens through the phone or cable lines, or even satellite.
00:00:51
This connection means that information from around the world can reach our computers.
00:00:56
If we could see the connection, the information coming through it would look like little packets of code.
00:01:01
It doesn't make sense to most people.
00:01:07
We need a translator, something that turns the packets of code into words and images we see on a website.
00:01:10
For this, we use a web browser.
00:01:16
It translates the information and makes it useful to us.
00:01:19
But that code has to come from somewhere, right?
00:01:23
If we could follow it to its home, we'd see that it's coming from another computer.
00:01:26
Not a regular computer, but one that's built to make webpages available.
00:01:30
It's called a server.
00:01:35
The words and images that appear on our screen live here in the server.
00:01:37
If there was only one server, this would be simple.
00:01:41
But there are millions of servers and webpages.
00:01:44
We need a way to find a specific page on a specific server.
00:01:47
We do this with web addresses.
00:01:51
Each server and website has a unique one.
00:01:54
As long as we have the right web address, we can visit a page on any server on the web.
00:01:57
The reason we call it a web is that all the servers are connected.
00:02:03
We can easily jump from one to the other using addresses via our web browser.
00:02:07
And we don't have to remember all the addresses.
00:02:12
Webpages use shortcuts or links.
00:02:14
Words and images we can click that direct us to page after page.
00:02:17
These links create a web of connections that are easy to navigate.
00:02:22
Together, this system makes up the World Wide Web.
00:02:26
So, let's sum it up.
00:02:31
To visit a website, we type in a web address or click a link.
00:02:33
The information for the website lives on a server.
00:02:37
It comes to us as little packets of code.
00:02:41
And our web browser translates this code into words, photos, music, videos, and links that help us get things done.
00:02:43
Yay!
