Specific course objectives

The course aims at explaining the functions and the architectures of modern operating systems. After a brief introduction on the history of operating systems and their relationship with computer technology, the course describes the problems and the main solutions for memory management (especially virtual memory), CPU scheduling and processes, deadlock and semaphores. Other main topics are I/O management, the file system and the services over networks (with examples from Internet). Particular evidence is given to distributed systems and some key aspect of security, criptography and network operating systems.
