Introduction to Advanced Operating Systems

Overview of operating system design principles

An operating system (OS) is a fundamental software layer that manages computer hardware resources and provides services to user applications.

Operating system design principles encompass fundamental concepts and methodologies guiding the development of efficient, reliable, secure, and scalable operating systems.

These principles address critical aspects such as resource management, scheduling algorithms, memory management, and communication protocols.

Review of basic concepts

Processes are running instances of programs, each with its own address space, execution state, and resources.

Threads represent lightweight execution units within a process, enabling concurrent execution and efficient resource sharing.

Scheduling involves the allocation of CPU time to processes and threads, aiming to optimize system performance and responsiveness.

Historical perspective and current trends

The history of operating systems traces back to the early days of computing, evolving from simple batch processing systems to sophisticated distributed and cloud-based architectures.

Key milestones include the development of groundbreaking systems such as UNIX, Windows, and Linux, each contributing to the evolution of operating system design and implementation.

Current trends in operating systems reflect the industry's shift towards containerization, microservices architecture, and serverless computing, driven by the demand for scalable, resilient, and agile software deployment solutions.
