Suitable for English-speaking students
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.
Organization, structure and typical functions of an operating system. Major components and services of an operating system.
Process concept. Process creation and termination. Process scheduling. Preemptive versus nonpreemptive scheduling. Scheduling criteria. Scheduling algorithms. Pipes.
Memory Management and Virtual Memory
Logical and physical address space. Contiguous memory allocation. Internal and external fragmentation. Segmentation. Paging. Virtual address space. Page-replacement algorithms. Frame-allocation models.
File System and Storage Devices
File system organization, structure and layers. File concept. Directory structure and hierarchy. File allocation methods. Free-space management. HDD and SSD disks. Disk scheduling algorithms.

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.
Distributed evaluation without final exam

Eligibility for exams
Skip no more than a quarter of the practical classes.
Grade in practical test >= 50%.
Calculation formula of final grade
Two theory tests - T1 and T2 - during the semester (each covering half of the theory).
One practical test (in computer lab) - TP.
Assuming the student has "frequência", the final grade is:
Grade = ( 6*TP + 7*T1 + 7*T2 ) / 20
If the student must do "exame de recurso" - ER - then the grade will be:
Grade = ( 6*TP + 14*ER ) / 20
(the exam will cover all the theory).
Contact the lecturer.
Due to the logistical and sanitary control difficulties imposed by the COVID-19 epidemic, I inform you that the evaluation for "Operating Systems" will be carried out ** only ** by final presential examination ("normal" and "recurso" epochs).
The dates and conditions in which these exams are going to be carried out are being studied by the direction and by the pedagogical council of FCUP and by the directions of the courses.
To be clear: ** there will be no computer test **
The evaluation of the practical component will be made in the exam with several questions about the exercises of the sheets of the practical classes or similar.
