    • Course Rationale

      Operating systems are central to computing activities. An operating system is a program that acts as an intermediary between a user of a computer and the computer hardware. Two primary aims of an operating system are to manage resources (e.g. CPU time, memory) and to control users and software. Operating system design goals are often contradictory and vary depending of user, software, and hardware criteria. This course describes the fundamental concepts behind operating systems, and examines the ways that design goals can be achieved.



    • Course Objective

        •  To learn the fundamentals of Operating Systems.
        • To learn the mechanisms of OS to handle processes and threads and their communication.
        • To learn the mechanisms involved in memory management in contemporary OS.
        • To gain knowledge on distributed operating system concepts that includes architecture, mutual exclusion algorithms, deadlock detection algorithms and agreement protocols.
        •  To know the components and management aspects of concurrency management.
        • To learn programmatically to implement simple OS mechanisms.


    • course outcome

        • CO1:  Able to explain the functions, facilities, structure of operating systems and fundamental operating system abstractions.
        • CO2:  Able to analyze the structure of operating system and design the applications to run in parallel either using process or thread models of different OS.
        • CO3: Able to analyze the performance and apply different algorithms used in major components of operating systems, such as scheduler, memory manager, concurrency control manager and mass-storage manager, I/O manager
        • CO4:  Able to analyze and justify the various device and resource management techniques, managing deadlock situations for timesharing and distributed systems.
