Objectives

The course aims to deepen the operating principles, the inherent problems and ways to overcome them in modern Operating Systems. It aims to consolidate the basic algorithms applied for the optimal operation of the OS, and introduces the student to more complex concepts, problems and solutions. They analyze issues such as scheduling processes, deadlocks, memory management algorithms, advanced topics file systems and computer systems security. Also deepens in architecture, design principles and construction and method of operation and capabilities of the OS UNIX for which made a detailed case study (case study). This study analyzed the history of Unix, o how to use and the key commands, the implementation process, the process scheduling, memory, input / output, file system, security of Unix, as well as selected management issues .
