Lecture Notes On Operating System by Sandeep
This paper highlights the major operating system concepts. It also covers essential functions, the history of OS, with particular services and an underlying computer system architecture. Major topics include Process Control Blocks, CPU Scheduling, Threads, further notes on Inter-process Communication, and several synchronization mechanisms, such as Peterson's solution, Synchronization Hardware, Semaphores. Besides these, it addresses highly complex issues such as the Readers-Writers Problem, including descriptions of both abstract and concrete solutions used for concurrent resource management.

The notes go into great detail of how operating systems have evolved and what kinds of operating systems exist today. The content ranges from basic-level ideas such as system calls, OS structure, and process management to important topics such as memory management, virtual memory, page replacement algorithms, and the theory that describes how deadlocks work, including detection, recovery, avoidance, and prevention. Both basic concepts and more advanced practice issues are found in the discussion of multiprocessor systems, I/O hardware and software principles, and file system management, including implementation and optimization strategies. This document proves to be very informative in terms of grasping the minute details of modern operating systems.

Lecture Notes On Operating Systems Mrs. Sk Abeeda
Mrs. Sk Abeeda's notes describe the basic concepts of the operating system. The material includes processes, threads, and scheduling. It gives a thorough view of such synchronization mechanisms and deadlocks besides memory management. File and I/O subsystems and protection mechanisms are also discussed, providing a comprehensive view of how operating systems work and how they manage resources. In short, it is a paper to allow one to gain a good grasp of the core principles of operating systems and to put them into practice.

Lecture Notes on Operating Systems by Marvin Solomon
Marvin Solomon's study notes outline the main topics of an operating system, which include discussion on Java-related matters, processes, synchronization, and memory management. Added to this is information about disk management, file systems, and protection and security. This is a small brief report with references in seeking knowledge for the essence of how an operating system should be managed and work.

Operating Systems An introduction to Unix, and Operating Systems Theory
The notes by Hugh Murrell provide a starting point in UNIX and operating system theory. Key topics include: UNIX file systems, networking, and process synchronisation. Inter-process communication under UNIX; including deadlock scenarios and concepts of virtual memory and paging are also covered. A good resource to explain both UNIX-specific features, as well as general operating system principles.

Operating System by Bighnaraj Naik
The Notes by Bighnaraj Naik hence, provide a directed discussion of operating systems, beginning with their history, and various types. The paper deals with critical services to an operating system in connection with management of processes, the idea of process synchronization, in-depth process management and scheduling, tools and constructs used in processing concurrency, detection of deadlocks, and prevention techniques. The paging technique and virtual memory management form the base of dynamic resource allocation techniques. File systems have also been discussed; they classified into logical and physical file systems with differences in their allocation strategies, so it has provided a profound insight into the theoretical and practical sides of the operating system.
