A Half Century of Internet: How it works today

The Internet connects more than half of the world’s population. This revolutionary form of transmitting all kinds of data between places on the planet has made the network of networks the indispensable backbone of societies. The number of users has exploded to four billion people.

The speed of change is dramatic and for some breathtaking. Many well-known and even more unknown personalities have shaped the development of the Internet. However, this exciting success story also reveals the dark sides of this development. What has become of the original hope for a democratization of communication? To what extent has the Internet provided access to better educational opportunities? How do large Internet companies and governments use the Internet? How can you safely communicate over this network?

At the end of this course, you will better understand the following contents:

  • What the technical construction principle of the Internet looks like in its main features
  • How data is transferred from one computer to another
  • How data packets find their way through the interconnected individual networks of the Internet
  • How mobile devices, sensors and machines communicate with each other via the Internet
  • Which applications ensure that you can surf the World Wide Web and send or receive e-mails or films
  • That security on the Internet – not considered a design feature from the outset – must be protected against possible attacks.
