Learning Outcomes

The purpose of the course is to familiarize the students with the basic concepts of operating systems, their design principles, the themes they manage and the impact of their various variants on the operation of systems.

In this context, the learning outcomes of the course, after its successful completion, are that the students will be able:

  • to understand the basic concepts of operating systems as well as the key areas / operating difficulties of a computational system that they are required to manage.
  • to know the basic mechanisms that an operating system implements in order to serve multiple processes, to manage memory and manage the file system.
  • to analyse, evaluate and justify alternative technologies / mechanisms of operating systems.
