Foundations of Operating Systems for Computer Science

Understanding how an operating system manages hardware and software is crucial for any aspiring software engineer, system administrator, or computer science student. This comprehensive text-based course guides you through the fundamental principles of operating systems, giving you the theoretical depth and practical insight needed for academic exams, technical interviews, and professional development. Through clear written explanations and structured analysis, you will build a complete mental model of how modern systems operate. You will start with foundational definitions and system architectures before progressing to the complex mechanisms that keep computers running efficiently. What you'll learn: 1. Learn the core components of an operating system, including kernels, system calls, and execution modes. 2. Understand process management, CPU scheduling algorithms, and inter-process communication. 3. Master memory management techniques, virtual memory, paging, and segmentation. 4. Explore concurrency, synchronization, deadlocks, and how to resolve them. 5. Practice analyzing file systems, storage structures, and I/O device management. 6. Discover modern OS concepts like virtualization, containerization basics, and security principles. This course begins with essential terminology and the historical evolution of operating systems before moving into deep-dives of CPU scheduling, memory management, and file systems through clear written explanations and step-by-step conceptual exercises. This course is designed for computer science students, IT exam aspirants, and self-taught developers looking to build a rock-solid foundation in system-level software. No prior operating systems knowledge is required. Start reading today to master the inner workings of modern operating systems.
