This note deals with what
operating systems are, and the context in which they operate. In particular, it
emphasizes the issues of software layers and abstraction, and the interaction
between the operating system and the hardware. Topics covered includes: Operating System Functionality,
Background on Computer Architecture, Processes and Threads, UNIX Processes,
Concurrency, Resource Contention and Deadlock, Lock-Free Programming, Memory
Management, File Systems, Mechanics of Disk Access, Crosscutting Issues, SMPs
and Multicore, Operating System Structure, Performance Evaluation, Communication
and Distributed Systems.
In this book, you will learn about all three kinds of interaction. This book describes how all these kinds of support are provided both by operating systems and by additional software layered on top of operating systems, which is known as middleware. Topics covered includes, Threads, Scheduling, Synchronization and Deadlocks, Atomic Transactions, Virtual Memory, Processes and Protection, Files and Other Persistent Storage, Networking, Messaging, RPC, and Web Services, Security.
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.
