Operating System Text Book

Operating Systems are the bridge between hardware and software, the guardians of resources, and the facilitators of user experiences. They are the complex software layers that manage memory, process scheduling, file systems, networking, and so much more. Understanding how they work is crucial for anyone in the field of computer science, software engineering, or IT.

Beyond the technical aspects, Operating Systems offer a rich history, reflecting the evolution of computing itself. From the early days of batch processing and punch cards to the modern, interconnected world of cloud computing and mobile devices, the story of Operating Systems is intertwined with the story of technology and innovation.

This book is divided into several chapters, each dedicated to a specific aspect of Operating Systems. We'll start with the fundamentals, exploring the core concepts and principles that underpin all Operating Systems. From there, we'll dive into the architecture of Operating Systems, discussing topics such as process management, memory management, and file systems.We will also explore how Operating Systems have evolved over time, from the early mainframes to the rise of personal computing and the emergence of mobile and embedded systems. Additionally, we'll delve into contemporary challenges and trends, including virtualization, containerization, and the role of Operating Systems in cloud computing.
