ECTS Credits
1st Cycle Studies

Recommended Prerequisites

Computer Programming; Data Structures and Algorithms; Microprocessors Systems.

Teaching Methods

Theoretical classes with presentation, using audiovisual means, of the concepts, principles, theories, and methodologies, and with the presentation of illustrative and application examples.

Practical laboratory classes, supervised by a professor: in these classes, some time is dedicated to the presentation of topics relevant to the practical handouts and to the laboratory works; And the rest of the time is dedicated to the development of practical handouts and laboratory works which require the application and combination of different concepts.

Learning Outcomes

Acquire knowledge about the internal functioning of operating systems (OS) and their modules, including, processes scheduling, memory management, virtual memory, disk scheduling, file systems, and concurrent programming; and basic knowledge about distributed systems. Acquire knowledge about techniques and algorithms related to operating systems. Acquire capacity to write good system code that explores in an optimized manner the functionalities of an operating system.

Acquiring competencies in analysis and synthesis, practical application of theoretical knowledge, solving problems, autonomous learning, adaptivity to new situations, informatics knowledge concerning the scope of study.
