Foundations of Operating Systems: Architecture and Core Concepts

Have you ever wondered how your computer coordinates multiple tasks at once without crashing, or how software communicates directly with hardware? Understanding the inner workings of operating systems is the key to unlocking efficient programming and robust system design. This text-based course guides you through the fundamental principles of operating systems, transforming abstract concepts into clear, actionable knowledge. You will explore how system resources are allocated, how processes are scheduled, and how modern architectures handle virtualization and security. What you'll learn: - Understand core kernel architecture, system calls, and the boundary between user and kernel space. - Manage processes, threads, and CPU scheduling algorithms to optimize performance. - Analyze memory management techniques, including virtual memory, paging, and address translation. - Explore file systems, storage allocation, and input/output communication protocols. - Learn modern virtualization concepts and how containerization isolates system resources. - Practice identifying concurrency issues like race conditions, deadlocks, and synchronization barriers through written conceptual exercises. You will start with fundamental terminology, historical context, and basic architectural definitions before moving step-by-step into process scheduling, memory virtualization, and modern container-level isolation. This course is designed for aspiring software engineers, computer science students, and curious self-learners with no prior operating systems experience. Begin your journey into the core of computer systems and build a stronger foundation for your technical career.
