====== Task 0 - Getting to know the architecture of GNS3 ======
In task 0 you will learn the basics of the architecture of GNS3 v2.0. The four components of GNS3 are introduced: 1) the user interface (GUI) (gns3-gui or gns3-web); 2) the controller (gns3-server); 3) the computer (gns3-server); 4) the emulators (Qemu, Dynamips, Virtualbox etc.).
===== Task 0.0 - Watch the introductory videos =====
Watch the introductory videos on GNS3. Don't be discouraged if you don't understand everything yet. As you progress through the course, the connections will become clear to you.
==== Introduction - What is GNS3? ====
In this short sequence you will learn a few basic facts about the network simulation software GNS3.
