Unit I
Introduction to operating systems: Overview – hardware protection – operating systems services – system calls – system structure – virtual machines.
Unit II
Process concepts – process scheduling – operations on process – inter-process communication – multi threading models – threading issues – thread types – CPU scheduling. Process synchronization: critical section problem – semaphores – classical problems of synchronization ––Deadlocks – deadlock characterization – methods of handling deadlocks – deadlock prevention – avoidance – detection and recovery.
Unit III
Storage management: memory management – swapping – contiguous memory allocation. Paging and segmentation – segmentation with paging – virtual memory – demand paging– page replacement
Objectives and Outcomes
Course Objectives
- The course aims at teaching students understand the structure and implementation of modern operating systems, virtual machines and their applications.
- It summarizes techniques for achieving process synchronization and managing resources like memory and CPU in an operation system.
- It compares 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).
- It gives a broad overview of memory hierarchy and the schemes used by the operating systems to manage storage requirements efficiently.
Course Outcomes
CO1: To understand the architecture and functionalities of modern Operating System.
CO2: To understand and apply the algorithms for scheduling.
CO3: To understand and apply the algorithms for resource management.
CO4: To apply semaphores and monitors for classical and real-world synchronization scenarios.
