-The following terms will be used throughout the following chapter:

-       \item Device, Client

-               These terms denotes the actual device connected to the system. This can
-               be a real device such as a microcontroller but it can also just be a
-               program on the same machine as the server functioning as a client.
-       \item Server, \gls{iTasks}-System
-
-               This is the actual executable serving the \gls{iTasks} application. The
-               system contains \glspl{Task} taking care of the communication with the
-               clients.
-       \item System
-
-               The system describes the complete ecosystem, containing both the server
-               and the clients including the communication between them.
-       \item Engine
-
-               The runtime system of the client is called the engine. This program
-               handles communicating with the server and runs the interpreter for the
-               \glspl{Task} on the client.
