Operating Systems Principles and System Architecture

Every piece of software you write depends on the underlying operating system to execute commands, manage memory, and interact with hardware. Understanding these internal mechanics is essential for writing efficient, secure, and scalable applications. This course provides a comprehensive introduction to the core principles of operating systems, transforming your perspective from a high-level programmer to a system-aware developer. You will gain a deep understanding of how modern systems handle multiple tasks simultaneously while maintaining stability and security. What you'll learn: - Understand the fundamental architecture of kernels, system calls, and hardware abstraction. - Master process management, thread synchronization, and CPU scheduling algorithms. - Learn memory management strategies including virtual memory, paging, and allocation. - Explore file system structures, storage management, and data persistence. - Apply modern security principles, including zero-trust concepts and access control. - Understand the foundations of virtualization and containerization used in modern cloud computing. The course begins with essential definitions and the historical evolution of system design, followed by detailed written explorations of resource management and modern architectural patterns. It is designed for beginners and aspiring software engineers who want to understand the logic behind computer behavior without any prior systems programming experience.
