About this unit

The Internet is part of nearly everything we do on a daily basis. But do you know how it all works? From WiFi to IP addresses to HTML to keeping information safe online, there’s a lot of important stuff going on that most of us don’t have the opportunity to learn more about. In six short, introductory videos, you’ll get an inside look into foundational concepts of everything from wires to websites, taught by guest lecturers including the actual “Father of the Internet” Vint Cerf, Tumblr founder David Karp, and creators on teams at Google, Spotify, XBox, Symantec, and more.
