The BBC is currently offering two interesting resources about the Internet. Mapping the Growth of the Internet is an interactive map that provides a visualization of the growth of the Internet around the world since 1998. How the Web Works is a fourteen slide slideshow that explains how the information you see displayed on website on your computer gets there. How the Web Works provides clear visuals and helpful captions where necessary.

Hat tip to Mashable for the link to Mapping the Growth of the Internet.

Applications for Education
How the Web Works could be a good resource for computer science teachers and anyone else needing to provide an explanation of the web to students.
