Learn how the internet works and gain insights into computer networking

The internet is the world’s biggest computer network. It connects almost everything, from people to machines, in all areas, from the art world to the stock exchange. It can be found almost everywhere on this planet and even beyond. It has become one of the most important infrastructures to modern life. But how does the internet actually work? After taking part in iLabX, you will not only understand the mechanisms behind the internet, but you will be able to create a modern network yourself on your own computer.

Why this program?

Each module first introduces the background of a relevant mechanism or tool. After learning the concepts through videos, texts, and interactive learning elements, you will be able to build your own fully-functional internet. Within the vLab virtual Internet laboratory, you will learn to use the same tools that also power the internet. Under close guidance, each module brings you closer to having a fully-functional internet running on your computer. As you will be applying existing internet mechanisms, you will even be able to connect your creation to the world wide web. In this way, after completion of the course, you can call yourself a true master of the internet.

The design of this course focuses on making it both exciting and continuously motivating. No matter what kind of learner you are, we are confident you will find the right learning experience! The videos explain everything in detail, but if you prefer reading instead, that’s also an option. There are many practical exercises – and of course the virtual laboratory – that allows you to configure the real Internet on your computer. Last but not least, there is an engaging story that runs throughout the course: Help the iLabees scale their honey sales, helping their business conquer the internet!
