The Internet is the backbone of the digital world. To understand the digital transformation in society, business and private live one needs to understand how Internet is working. To this end the prep course provides the Internet basics. 


The course explains the functioning of different types of computer networks and how such computer networks can be interconnected to form a virtually homogeneous net, the Internet. To this end intermediate systems like router and gateways are needed, and software, so-called communication protocols. The protocol stack that is used to form the Internet is the TCP/IP stack, consisting of protocols like IP, TCP, and a big number of application protocols like HTTP, SMTP, DNS, and many others which connect Internet applications and services like the WWW with the Internet.
