Operating Systems

Updated: Oct 18



This course provides a comprehensive overview of operating system concepts and principles. It covers modern operating systems' fundamental components and functionalities, including process management, concurrency control, scheduling, memory management, file systems, I/O management, and security. The course begins by introducing the definition, history, and types of operating systems and the key services and structures they provide. It then delves into the concepts of processes and threads, including their states, control, and synchronization. Subsequent chapters explore the challenges of process synchronization, such as the critical-section problem, mutual exclusion, and classic synchronization problems.


The course also covers scheduling algorithms and criteria for evaluating their performance. A significant portion of the course is dedicated to the important topic of deadlocks, including their characterization, detection, recovery, avoidance, and prevention. The course then examines various memory management techniques, such as swapping, virtual memory, page replacement, and segmentation. The file system, I/O management, and storage management chapters provide insights into the organization, implementation, and principles underlying these key operating system components. Finally, the course concludes with an in-depth look at operating system security, including threats, vulnerabilities, and access control mechanisms.


Course Objectives:

  • Understand the fundamental concepts, functions, and evolution of modern operating systems.

  • Describe the key components and structures of operating systems, including process management, concurrency control, and synchronization.

  • Analyze and apply scheduling algorithms and criteria to manage processes and threads effectively.

  • Identify and resolve deadlock situations using various deadlock characterization, detection, avoidance, and prevention techniques.

  • Examine the principles of virtual memory management, including paging, page replacement algorithms, and segmentation.

  • Comprehend the organization and implementation of file systems, input/output management, and storage management.

  • Recognize security threats and vulnerabilities in operating systems, and apply access control mechanisms to protect system resources.

  • Apply the theoretical concepts learned in the course to analyze operating system components through hands-on projects and assignments.
