Computer Programming Computer Structure

The aim of this course is that the student knows the role of extended machine operating system, the services offered by the rest of the system and its main components and entities (processes, memory, files, etc.), the concepts of competition and relations with the rest operating system software and computer hardware. To achieve this goal the student must acquire a number of generic skills, knowledge, skills and attitudes. 1 Transversal / Generic Skills 1.1 Capacity for analysis and synthesis 1.2 Ability to organize and plan 1.3 Troubleshooting 1.4 Teamwork 1.5 Ability to apply knowledge in practice 2 Specific Skills 2.1 Cognitive (Know) - Knowledge of the concepts of SS.OO - Knowledge of the organization and operating system services as extended machine - Knowledge of the concepts of concurrency - Understanding the effect of the operating system on the rest of the system. - Techniques for programming calls to operating systems - Knowledge of methods of resource management in an operating system 2.2 Procedural / Instrumental (Know how) - Programming with calls to operating systems - Programming concurrent applications - Design of the operating system utilities - Use monitoring tools operating systems 2.3 Attitudinal (Be) - Ability to generate new ideas (creativity) - Critical attitude regarding current operating systems - Concern for quality operating systems - Achievement motivation - Interest in research and seek solutions to new problems related to operating systems.

- Theoretical classes: 1.5 ECTS. They aim to achieve specific cognitive skills of the subject. In them the knowledge that students should acquire will be presented. To facilitate their development students receive class notes and have basic reference texts that allow them to complete and deepen those subjects in which they are most interested. - Practical classes: 1.5 ECTS. Instrumental develop specific skills and most of the cross, such as teamwork, ability to apply knowledge to practice, to plan and organize and analysis and synthesis. Also they aim to develop the attitudinal specific capabilities. Is the design and development of a shell with concurrency with several new commands to the operating system. They developed in working groups and in computer classes with teacher presence. - Guided academic activities with presence of the teacher: 1 ECTS - Resolution of exercises and case studies of participatory in class. It may further include the study of examples of operational systems common answers to the exercises and joint correction, presentation of papers, etc. - Student study: 1.5 ECTS. Exercises and readings proposed by the teacher. Personal study - Exercises and exam: 0.5 ECTS. They intended to influence and complement in the development of cognitive and procedural specific capabilities.
