Learning objectives
<br />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.
Prerequisites
<br />Computer System Architecture <br />C and Java Programming (suggested)
