Programming Computer Structure

The goal of the course is to allow the student knowing the functioning of the operating system as a expanded machine, its services for the system and its components, the major entities (processes, memory, files, etc.), concurrency, and the relations of the operating systems with the sw and hw of the computer. To achieve this goal, the student must acquire the following program outcomes (PO): a, b, c, d, e, f, g, h, i, k. Related to the following competences: 1.- General competences - Analysis and synthesis (PO: b, e, g) - Planning and organization (PO: b, c, h) - Problem solving (PO: a, e, k) - Collaborative work (PO: d) - Capacity to apply theoretical concepts (PO: a, b, c, e, f, i, k) 2.- Specific competences (CECRI5, CECRI10). 2.1.- cognitive (PO: a, b, c, e, f, h, k) - Operating system concepts - Knowing the main features, functionality, and structure of the Operating Systems. - Concurrency concepts - Operating system programming and design of applications based on OS services. - Resource management in operating systems 2.2.- Instrumental (PO: b, c, e, k) - Programming with operating system calls - Programming concurrent applications - Desinning utilities on the operating system - Using tools to monitorize and management of the operating systems 2.3 Attitude (PO: e, g, h, i) - Creativity - Critical vision of the operating systems - Quality aspects and operating systems - Motivation - Interest for finding new solutions with operating systems

- Theory: lectures & exercises 1.5 ECTS. (PO: a, b, e, f, g, h, i, k) * Operating system theoretical concepts related to the program, professional aspects, importance of the subject, critical vision of the operating systems and quality aspects, information acquisition and lifelong learning recognition. * OS problems formulation and resolution. Analysis and synthesis. Applying technical knowledge to solve operating systems problems. * Examples during the lectures to show the students the professional and legal responsibilities due to system failures because of OS, and their economic repercussions. * Examples in the lectures to show the students the impact of choosing an OS solution in the enterprise economic context. * Communication skills are enhanced through reading of materials and written exams. - Projects. 1.5 ECTS. (PO: a, b, c, d, e, g, k) * Several projects are made along the course applying computer systems principles to the field of computer engineering. Partial teacher support. * Projects are developed through a design problem under initial specifications, where the students have to analyze requirements and provide a working solution. * Students are required to use OS tools and provide solutions to real-world problems. Use of professional tools for Linux and Windows OS for solving OS projects. * They develop collaborative work, capacity to apply theoretical concepts, and capacity to make an experiment in time meeting desired needs. * Communication skills are enhanced through writing of memory projects in English and Spanish. - Academic activities with the teacher. Lab experiments. 1 ECTS. (PO: b, d, e, g, k) * Students must design and execute lab experiments with teacher support, such as OS monitoring, system installation, etc. * To extract conclusions, they must also analyze, and interpret data. * Students are required to use OS tools and provide solutions to real-world problems. Use of professional tools for Linux and Windows OS for solving OS projects. * They develop collaborative work, capacity to apply theoretical concepts, and capacity to make an experiment in time meeting desired needs. - Student work. 1.5 ECTS. (PO: a, b, c, d, e, f, g, h, i, k) * Self-study to understand the theoretical concepts and how to apply them to solve operating systems problems. * Homework, individually or cooperatively, to finish the OS projects requested along the course. * Information acquisition and study to know new solutions with operating systems and to recognize the importance of OS in the Computer Engineering field, and the changing world of OS and the need of lifelong learning to be an active professional. - Exams. 0.5 ECTS.
