Chapter List
Chapter 1: Introduction to Operating System
Covers computer system, OS objectives and role, mainframe systems (batch, multiprogrammed, time sharing), single and multiprocessor systems, distributed and clustered systems, real-time systems, interrupts, OS modes, I/O structure, OS components, kernel, and system calls.
Chapter 2: Process Management
Explains process definition, attributes, states, state transitions, process control block, process scheduling, scheduling queues, dispatching, context switch, process creation and termination, and inter-process communication (IPC).
Chapter 3: Threads
Covers threads, benefits, difference between processes and threads, multithreading, types of threads (kernel-level and user-level), multithreading models (many-to-one, one-to-one, many-to-many), and thread libraries.
Chapter 4: CPU Scheduling
Explains CPU scheduling, multiprogramming, scheduling objectives, CPU/I/O burst cycle, preemptive and non-preemptive scheduling, scheduling algorithms (FCFS, SJF, Priority, Round Robin, Multilevel Queue, Multilevel Feedback Queue), and algorithm evaluation.
Chapter 5: Process Synchronization
Covers race conditions, critical-section problem, solutions and algorithms, semaphores, classic synchronization problems (Producer-Consumer, Readers-Writers, Dining Philosophers, Sleeping Barber), counting semaphores, and monitors.
Chapter 6: Deadlocks
Explains deadlock definition, examples, resources, deadlock characterization, resource-allocation graph, methods for handling deadlocks, deadlock prevention, avoidance (Banker’s algorithm), detection, and recovery.
Chapter 7: Memory Management
Covers memory management requirements, relocation, protection, sharing, loading and linking, swapping, memory allocation methods, contiguous and non-contiguous storage allocation, logical vs physical address space, paging, and segmentation.
Chapter 8: Virtual Memory
Explains virtual memory, demand paging, page faults, page replacement algorithms (FIFO, Optimal, LRU, NRU, LRU Approximation), frame allocation, thrashing, working set, and page size considerations.
Chapter 9: File System Management
Covers file attributes and operations, file system objects, access methods, file locking and blocking, file protection, file system reliability, file management module, directories and naming, directory structures, and directory entries.
Chapter 10: I/O and Device Management
Explains I/O management, buffering, spooling, handshaking, interrupts, interrupt priorities, I/O devices, storage hierarchy, hardware and software organization, caching, and device drivers.
Chapter 11: Operating System Security
Covers security problems, authentication (passwords, encrypted passwords), prevention, detection, correction, identification, program threats (Trojan horse, trap doors), system threats (worms, viruses), threat monitoring, and system security.
Chapter 12: Case Study: Linux
Explains Linux history, features, distributions, Linux architecture and system structure, process scheduler subsystem, memory manager subsystem, virtual file system, inter-process communication, and network interface.
Chapter 13: Data Communications and Networks
Covers data communication, transmission modes, analog and digital data, modulation, serial/parallel transmission, computer networks, client-server architecture, types of networks (LAN, WAN, MAN), wireless networks, topologies (Bus, Star, Ring, Tree, Mesh), network standards, protocols, TCP/IP, Bluetooth, Wi-Fi, WiMAX, WAP, switching types, and communication devices (modem, NIC, bridge, hub, switch, routers).
