The course introduces the main concepts applied to operative systems. Students are expected to comprehend the internal structure of the computational system and the mode of operation of operative systems, so as to acquire knowledge of computational systems which facilitates the comprehension and solution of IT problems.
1. Comprehends and explains the basic theoretical concepts subjacent to the functioning of modern operative systems, as well as their evolution throughout the years.
2. Comprehends and explains the most important concepts of management of processes, memory management, systems of files, protection and safety and applies the concepts in solving problems which are typical in systems administration.
3. Performs basic operations of administration of processes, memory, file systems and protection in Linux and Windows;
4. Performs advanced administration operations of message management services and periodical execution of commands in Linux.
