Operating Systems Fundamentals: Core Architecture and Design Principles

Every software developer interacts with an operating system daily, yet its inner workings often remain a black box. Understanding how the OS manages hardware resources is key to writing efficient, secure, and high-performance applications. This text-based course bridges the gap between high-level programming and low-level system design, guiding you through the elegant engineering solutions behind resource allocation and hardware abstraction. What you'll learn: Understand the historical evolution of operating systems and the engineering challenges they solve; Analyze the distinction between kernel space and user space to understand system security; Explore process management, threads, and CPU scheduling algorithms; Master memory management concepts, including virtual memory and paging; Examine file systems, input/output operations, and storage abstraction; Discover modern virtualization technologies and containerization primitives like namespaces and cgroups. You will start with foundational definitions and the history of system design before diving deep into core subsystems like memory, processes, and storage. This course is designed for beginner programmers, computer science students, and curious tech enthusiasts, with no prior systems programming experience required. Expand your technical foundation and discover the architectural principles that power modern computing.
