Learning objectives

This class introduces the fundamental principles and concepts that constitute the Operating Systems. We analyze the techniques for handling and for the coordination of system resources, in order to model a physical machine as an abstract device, for user convenience.
The Lab class offers an introduction to Operating Systems, with a particular focus on linux and unix based systems. The goal is to provide a method and the tools to program the shell and control the system (C).
