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, indepth 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.
