CENTRALISED SYSTEMS

1 - Knowledge and Ability to Understand ( Knowledge and Understanding ) , the goal is to raise awareness of all the problems and solutions related realtive computer use in large government organizations , business and banking . in particular of Operating Systems and technologies historically and currently used for this purpose . In particular, it puts emphasis on the optimization of the IT infrastructure and related costs through resource virtualization processes .

2 - Ability to apply knowledge and understanding - ( applying Knowledge and Understanding ) , the student acquires basic knowledge for sizing systems and design systems and Cluster stations with business continuity systems . Furthermore it will exert on the dimensioning of virtualized systems of homogeneous type or heterogeneous in order to improve performance and costi.Infine will have the basic ability to operate on systems .

3 - Rating of Autonomy . ( Making judgments ) . the basis for the platform Selection processes are provided so that the student is able to choose the platform best suited to a given application informatice and assess non-functional requirements .

4- Communication skills ( communication skills ) : the student will acquire the necessary communication skills and expressive appropriateness in the use of technical language in the context of the central systems .

5 - Learning skills ( learning skills) : The course aims , as the goal, to provide students with the necessary theoretical and practical methods to deal independently and solve new problems that may arise during a work activity . For this purpose, different topics will be covered in class , referring to practical cases drawn directly from the professional experience of the teacher.
