Operating Systems

Objectives

The operating system is the core component of any computer system. Therefore, aim of this course is to provide students with the fundamental concepts that underpin the design of current operating systems. We will study the models of computation offered by operating systems, your organization, primitive operations and elementar programming. Some of these concepts will be consolidated with details of real systems.

Thus, it is intended that the student knows the basic concepts underlying operating systems, with emphasis on their mechanisms and algorithms, as well as the internal structure of the operating systems most relevant. Set at the system level, using all the features of operating systems taking into account the sequential programming models and competitor.
