Teaching Methods

The Theoretical classes (T) will have detailed exposition, using audiovisual media, of the main concepts, principles and theories of Operative Systems, complemented with practical examples that create awareness and interest from the students on the topics at hand and are illustrative real world systems. The Theoretical-Practical (TP) classes will have detailed exposition of the Linux application development environment. Classes will include demonstrations and problem resolution activities. In Practical-Laboratorial (PL) classes, students will develop several group projects that require the application of theoretical knowledge and promote critical thinking. 

Learning Outcomes

This unit is a basic Operative Systems (OS) course. An OS should support an environment for the development and execution of programs, an interface for accessing the internal computational system (Programming API) and managing the hardware and software computational resources: Processors, Memory, Peripherals, Information (data and programs) stored in the Filesystem. The goal of this course is to present the students with the understanding of how modern OS work and to enable students to develop system applications that directly use the OS API and that explore the concurrency and multi-program features of the system. This course promotes the acquisition of competences through analysis and synthesis, problem solving, practical application of theoretical knowledge, autonomous learning, oral and written communication, critical thinking and decision making.
