Objectives

Provide students with the fundamental concepts of the theory and practice of the organization, structure and operation of an operating system.
Be able to implement parts of an operating system and write programs using the API of an operating system.

Learning outcomes and competences

At the end of the course, the students are expected to know:

• A historical perspective of the evolution of operating systems;
• How the major components of an operating system work;
• How an operating system interfaces the hardware;
• Different types and structure of operating systems;
• The programming interface of an operating system;
• How to write programs using the programming interface of an operating system;
• How to implement parts of an operating system.

Teaching methods and learning activities

In the lectures the fundamental concepts of operating systems are presented and discussed.

In the practical classes, students will get hands-on experience in programming over an operating system programming interface.

Eligibility for exams

Students must attend at least 2/3 of the practical classes.

Calculation formula of final grade

Students are assessed by their performance in the following components:

- Two practical exams to be realized during the semester. The grade of each is 3/20 (15% of the final grade).

- A written examination in the final of the semester. The grade of this component is 14/20 (70% of the final grade).

Examinations or Special Assignments

Students are assessed by their performance in the following components:

- Two practical exams to be realized during the semester. Each exam consists on implementing part(s) of a more wide project, developed in the weeks prior to the exam date, using the same tools and development environment.

- A written examination in the final of the semester consisting of questions similar to the ones solved during the theoretical and practical classes.
