About this course: The impact of technology and networks on our lives, culture, and society continues to increase. The very fact that you can take this course from anywhere in the world requires a technological infrastructure that was designed, engineered, and built over the past sixty years. To function in an information-centric world, we need to understand the workings of network technology. This course will open up the Internet and show you how it was created, who created it and how it works. Along the way we will meet many of the innovators who developed the Internet and Web technologies that we use today. What You Will Learn: After this course you will not take the Internet and Web for granted. You will be better informed about important technological issues currently facing society. You will realize that the Internet and Web are spaces for innovation and you will get a better understanding of how you might fit into that innovation. If you get excited about the material in this course, it is a great lead-in to taking a course in Web design, Web development, programming, or even network administration. At a minimum, you will be a much wiser network citizen.

Really great course! Dr Chuck's explanations are clear and makes the material very approachable. Another great thing about the course is that there are several interviews with the inventors and innovators in the Internet world. I highly recommend taking this course, even if it just for the sake of curiosity!

Excellent course! I love the interviews. Also, I think it's a great structure of going through the internet layer multiple times, first with a historic perspective, then with a more technical perspective.

Very interesting and a useful and comprehensive background in the nature of technology for non-techie people.

Great teacher, great course, first ever completed online.
