Operating Systems Fundamentals: Architecture, Services, and Management

Every software application relies on an operating system to interact with hardware, manage memory, and execute tasks. Understanding these underlying mechanisms is essential for writing efficient, system-aware code and troubleshooting complex software behavior. This text-based course guides you through the core components of modern operating systems, transforming how you view software execution, resource allocation, and hardware interaction. What you'll learn: - Understand the core responsibilities of an operating system, including kernel modes, system calls, and hardware abstraction - Analyze process management, CPU scheduling algorithms, and how systems handle concurrency and synchronization - Explore memory management techniques, virtual memory, paging, and segmentation - Examine file systems, storage management, and input/output device handling - Learn modern virtualization and containerization concepts from an operating system perspective - Discover fundamental system security principles, access control, and resource protection You will begin with foundational definitions and system structures before progressing to process coordination, memory allocation, storage design, and modern virtualization concepts. This structured progression is reinforced through detailed written explanations and conceptual exercises. This course is designed for beginner programmers, computer science students, and IT enthusiasts who want to build a strong foundational knowledge of system architecture without any prior operating system experience.
