Professional Electives Other Branches

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

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.
