This course has two components: a theory component to teach you the concepts and principles that underlie modern operating systems, and a practice component to relate theoretical principles with operating system implementation. In the theory component, you will learn about processes and processor management, concurrency and synchronization, memory management schemes, file system and secondary storage management, security and protection, etc.


CLO: 1. Understand fundamental operating system abstractions such as processes, threads, files, semaphores, IPC abstractions, shared memory regions, etc.
CLO: 2. Analyze important algorithms eg. Process scheduling and memory management algorithms C3 [Investigate].
CLO: 3. Categorize the operating system’s resource management techniques, dead lock management techniques, memory management techniques.C5.
CLO: 4. Demonstrate the ability to perform OS tasks in Red Hat Linux Enterprise. P4. (Mechanism / Guided Response).
