Course description
iLabX – The Internet Masterclass
The Internet is the world's biggest computer network. It connects everything, from people to machines, in all areas, from the art world to the stock exchange, everywhere on this planet and beyond. It has become one of our most important infrastructures. But how does this Internet that enables so many things in our daily lives actually work? After taking part in iLabX, you will not only understand the mechanisms behind modern computer networks, but you will create the Internet yourself on your own computer!
iLabX uses an award-winning methodology to teach you how the Internet works. Starting with the physical cables, you will learn, in six parts:
- what exactly happens when you open a website in your browser or send a chat message to a friend,
- how to set up a webserver yourself,
- how the ongoing transition between the “old” Internet version and its current successor can be so seamless, and
- key security concepts
