To thrive in today’s digital world, you need to understand the system that powers it. This course, built in collaboration with Google, will explore the internet and show you how it works. This class focuses on hands-on learning of important topics like cybersecurity, networking, and programming. By the end, you’ll be able to evaluate your options for a rewarding career in technology. At minimum, you’ll be a much wiser network citizen.



There’s no better way to understand the workings of the web, internet and applications than by building something yourself! We build a simple website from scratch, customizing it to our own design and use case. No coding experience needed.
Applications and the Web: What do the apps we use rely upon? The World-Wide-Web was invented in 1989 and by 1994 - “the year of the web” - the web was being widely use and Internet usage was growing by leaps and bounds. The late 1990’s saw the web and Internet used increasingly to revolutionize how business was done. Companies like Amazon, Facebook and TikTok were founded and grew very rapidly.
Dawn of Computing and The First Internet: World War II emphasized the strategic importance of computation, communication, and information, before the rise of the first internet, NSFNet, in the 1960s and 1970s for the US Department of Defense.
Networking: The Internet is designed based on a four-layer model. Each layer builds on the layers below it.
Emerging Technologies: The rise of disruptive new technologies such as 5G, the Internet of Things (IoT) and Artificial Intelligence (AI) are reshaping how societies and businesses use the internet and digital technology.
Personal and Web Security: We apply the basic ideas of encryption and signing to who we actually secure the connections that we use on today’s Web and Internet.
Encrypting and Signing: Using simple examples, we examine how to shield data from prying eyes and making sure that the data was not altered while in transit.
This course is delivered online through an institution of the Lower Cost Models Consortium (LCMC) that is different than your degree-granting institution that awards the academic credit for the course.
