Explaining the Internet

Introduction​

In this session, we'll discuss some networking fundamentals. By doing so, we'll lay the foundations for some of our later sessions regarding networking and the internet, such as (Re)Discovering the Browser and Hacking the Web.

Moreover, we'll explain what happens when you access a URL (we'll also learn how to do this from our terminals). Last but not least, we'll see what those ssh commands you've been using in order to solve the remote challenges mean.

Reminders and Prerequisites​

For this session, you'll need:

  • a working internet connection;
  • a Linux environment that you're comfortable working with;
  • to understand what a process is;
  • general knowledge of the Linux CLI, as discussed in session Welcome to Linux.
