The teaching of the course will be divided into three parts: a theoretical part with the exposition and explanation of the theoretical foundations, a practical part with solving exercises, and a laboratory part with the use of equipment and software that consolidates the learning results. The assessment of the course will focus on these three aspects. It will have a written test, worth 20 points. In this written test, the theoretical part will have a value of 7 values, and the practice of 13 values. Laboratory work will also be quoted at 20 points. The final grade is obtained through the average of the grades of the written test and the laboratory work.

This course aims to provide knowledge on the structure and functioning of operating systems. Namely, the acquisition of knowledge related to the creation of processes and threads, and the different forms of intercommunication between them. The student must also acquire the ability to resolve issues associated with synchronization in access to resources, in order to avoid potential potentially conflicting requests. Students who successfully complete this course will become familiarized with the most important aspects of operating systems operation, and will acquire the ability to develop applications that make use of an Operating System’s programming interface.
