Here you find all info about running ilab courses.
In February 2016 my friend Michael Folgmann from the -back then- Medienzentrum visited me in Garching to introduce me to the wonderful world of electronic live feedback mechanisms in the classroom. He also informed me that there would be a new call for project proposals regarding the new Massive Open Online Course (MOOC) format at…
The Internet affects many aspects of your daily life. However, you might not know how this important backbone of our digital society technically works. Take part in our free online course “iLabX – The Internet Masterclass” to learn how the Internet works! 7x 4-6h and we will build the Internet together with you on your…
Layer 2 only allows communication between directly connected hosts. Only with the help of the Network Layer communication over multiple hops becomes possible. The following image depicts where the Network layer is placed in the vLab network model: The most relevant Layer 3 protocol, which basically the most relevant protocol for the complete vLab /…
Look around you. How many things you see are connected to the Internet? How many things did you buy on the Internet? How many things were produced by companies that are connected over the Internet? How many things are there that never got in contact with the Internet? Are you sure? Didn’t they even have…
Layer 2, called the Data Link Layer, is responsible for exchanging data via so called frames between two directly connected hosts. On sending Layer 2 hands over a frame to the Physical Layer which encodes its as signals and sends it over the chosen medium. Layer 1 on the receiver side decodes the signals again…

Layer 1, also referred to as Physical Layer, is the lowest layer of the vLab model: It forms the link between networking hardware and the physical medium connecting two devices. The connection can rely e.g. on a copper cable, electromagnetic waves (wlan) or fiber.The sender of a message has to encode the information as signal…
Historically two major layered network architectures emerged as reference models known today: The ISO/OSI and the TCP/IP models. The TCP/IP model was the first approach to structure network communication using 4 different layers. The ISO/OSI model followed later, offering a even more detailed model with 7 different layers. For the iLabX – The Internet Masterclass…
