I have actually used this video for years now, and even though it’s 10 years old the information is still very applicable. I know a lot of people aren’t quite sure how the internet works, even though they use it basically non-stop everyday. This simple video (with what I think are great visuals) really does an amazing job at getting the basics to someone very quickly. If you want to then delve deeper into the internet, you only have to wiki some of the things he quickly mentions (routers, switches, ISP, etc). Thought I would just post it because of its usefulness.
