Home > Science Worksheets >About the Internet

The Internet is basically a bunch of computers that can talk to one another. We may just think the Internet is a place to help us do our homework or share pictures and images, but it is much more than just that. When the Internet first fired up, it was primarily just for scientists to share information to better understand what they were working on it. Today just under half of the human world has access to and is actively using the Internet in their daily lives. As time goes on, the Internet will be as accessible as a telephone.

We start with the history of the Internet, move on to how it works, and we end with where we think the Internet will go next.
