Advanced Operating Systems - Teoria (2008/2009)

Learning outcomes

The course covers advanced concepts related to operating systems, particularly focusing on distributed and real-time operating systems. Theoretical aspects will be further investigated with practical applications in laboratory.
The course consists of 32 hours of front lectures and 12 hours of practical applications.
Theaching material will be provided by the theacher during the course.

The final examination consists of a written (oral) test containing theoretical questions and exercises.
The test is passed with a grade of at least 18/30. The maximum grade is 30/30. The oral is optional.
