Course Objectives

• To make the students to understand the structure and implementation of modern operating systems, virtual machines and their applications.
• To summarize techniques for achieving process synchronization and managing resources like memory and CPU in an operation system.
• To compare and contrasts the common algorithms used for both pre-emptive and non-pre-emptive scheduling of tasks in operating systems (such a priority, performance comparison, and fair-share schemes).
• To give a broad overview of memory hierarchy and the schemes used by the operating systems to manage storage requirements efficiently.

Course Outcomes

• CO1: Understand the architecture and functionalities of modern OS.
• CO2: Understand and apply the algorithms for scheduling.
• CO3: Understand and apply the algorithms for resource management
• CO4: Apply semaphores and monitors for classical and real-world synchronization scenarios
