Introduction




Before we dive into the details of the book, let's first define what an operating system is, why it is important to study it, and what are the main features of modern operating systems.


What is an operating system?




An operating system (OS) is a software program that manages the hardware and software resources of a computer system. It provides a set of services and interfaces that allow users and applications to perform various tasks, such as creating files, running programs, accessing the internet, printing documents, etc. An operating system also handles the allocation and sharing of resources among different users and processes, such as memory, CPU, disk space, network bandwidth, etc. An operating system also ensures the security and reliability of the system by preventing unauthorized access, detecting errors, recovering from failures, etc.


Why study operating systems?




Operating systems are essential for the functioning of any computer system, from personal computers to smartphones to supercomputers. Studying operating systems can help you understand how computers work at a low level, how they interact with other devices and networks, how they support various applications and services, and how they cope with various challenges and demands. Studying operating systems can also help you develop skills in programming, problem-solving, debugging, testing, design, analysis, etc. Moreover, studying operating systems can expose you to many interesting and relevant topics in computer science, such as concurrency, synchronization, distributed systems, virtualization, security, etc.


What are the main features of modern operating systems?




Modern operating systems have evolved significantly over time to meet the changing needs and expectations of users and applications. Some of the main features of modern operating systems are:



  • Multiprogramming: This feature allows multiple programs to run simultaneously on a single processor or a multiprocessor system. Multiprogramming increases the utilization and efficiency of the CPU by switching among different programs according to their priority and resource requirements.



  • Multiuser: This feature allows multiple users to access and use the same computer system at the same time or at different times. Multiuser operating systems provide mechanisms for user authentication, authorization, accounting, protection, etc.



  • Multitasking: This feature allows a single user to run multiple applications or tasks concurrently on a single computer system. Multitasking enables users to perform various activities without waiting for one task to finish before starting another.



  • Real-time: This feature allows an operating system to respond to external events or stimuli within a specified time limit. Real-time operating systems are used for applications that require strict timing constraints, such as embedded systems, control systems, multimedia systems, etc.



  • Distributed: This feature allows an operating system to run on multiple computers that are connected by a network. Distributed operating systems enable users and applications to access and share resources and services across different machines, such as files, printers, databases, etc.



Overview of the book




Now that we have a basic understanding of what an operating system is and why it is important, let's take a look at the book Modern Operating Systems by Andrew S. Tanenbaum. In this section, we will describe the structure and organization of the book, the content and coverage of the book, and the target audience and prerequisites of the book.


Structure and organization




The book is divided into four parts, each consisting of several chapters. The four parts are:



  • Introduction: This part provides an overview of the history, structure, and functions of operating systems. It also introduces some fundamental concepts and terminology related to operating systems, such as processes, threads, scheduling, synchronization, deadlocks, memory management, virtual memory, file systems, input/output, etc.



  • Processes: This part focuses on the management and coordination of processes and threads in an operating system. It covers topics such as interprocess communication, classical synchronization problems, semaphores, monitors, message passing, remote procedure calls, distributed mutual exclusion, distributed deadlock detection, distributed agreement algorithms, etc.



  • Memory: This part deals with the allocation and protection of memory in an operating system. It covers topics such as segmentation, paging, swapping, demand paging, page replacement algorithms, working set model, thrashing, memory-mapped files, copy-on-write mechanism, shared memory segments, etc.



  • File Systems: This part discusses the design and implementation of file systems in an operating system. It covers topics such as file attributes, file operations, directory structures, file system implementation techniques, disk space management techniques, disk scheduling algorithms, disk reliability techniques, file system security and protection mechanisms, network file systems (NFS), distributed file systems (AFS), etc.



The book also includes two appendices that provide additional information on some topics related to operating systems. The appendices are:



  • The Mach System: This appendix describes the design and features of Mach, a microkernel-based operating system developed at Carnegie Mellon University in the 1980s and 1990s. Mach was one of the first operating systems to support multiprocessor systems and distributed computing.



  • The Windows 2000 System: This appendix describes the architecture and components of Windows 2000 (also known as Windows NT 5.0), a popular commercial operating system developed by Microsoft in the late 1990s and early 2000s. Windows 2000 was one of the first operating systems to support 32-bit and 64-bit processors and multiple user interfaces.



Content and coverage




The book covers a wide range of topics related to operating systems in a comprehensive and up-to-date manner. The book provides both theoretical and practical aspects of operating system design and implementation. The book also includes many examples and case studies from real-world operating systems to illustrate the concepts and techniques discussed in the book. The book also provides many exercises and projects at the end of each chapter to help readers test their understanding and apply their knowledge.


The book covers both traditional and modern topics in operating systems. Some of the traditional topics include process management (creation, termination, scheduling), synchronization (mutual exclusion, critical sections), deadlock (detection, prevention, avoidance), memory management (allocation, protection, virtualization), file systems (organization, implementation, security), input/output (devices, drivers, performance), etc. Some of the modern topics include distributed systems (communication, coordination, consensus), multiprocessor systems (symmetric, asymmetric), multicore systems (parallelism, concurrency), real-time systems (hard, soft), embedded systems (constraints, challenges), security (threats, mechanisms), virtualization (hypervisors, containers), cloud computing (services, models), etc. Target audience and prerequisites




> Operating System Concepts by Abraham Silberschatz, Peter Baer Galvin, and Greg Gagne, or Operating Systems: Internals and Design Principles by William Stallings. This book covers more topics and concepts than most intermediate textbooks on operating systems, such as Operating Systems: A Modern Perspective by Gary Nutt, or Operating Systems: Principles and Practice by Thomas Anderson and Michael Dahlin. This book also provides more examples and case studies than most advanced textbooks on operating systems, such as Advanced Programming in the UNIX Environment by W. Richard Stevens and Stephen A. Rago, or Distributed Systems: Concepts and Design by George Coulouris, Jean Dollimore, Tim Kindberg, and Gordon Blair. Therefore, this book can be considered as a comprehensive and in-depth textbook on operating systems that can suit different levels of readers.


Another difference between this book and other textbooks on operating systems is the style and approach. This book adopts a clear and concise style that makes it easy to read and understand. The book also uses a bottom-up approach that starts from the basics and builds up to more complex topics. The book also balances between theory and practice, providing both rigorous explanations and practical examples. The book also encourages readers to think critically and creatively, providing many exercises and projects that challenge them to apply their knowledge and skills. Therefore, this book can be considered as a user-friendly and engaging textbook on operating systems that can stimulate interest and curiosity.
