Core Concepts of Operating Systems: Processes and Resource Management

Do you want to understand the invisible layer of software that makes your computer work? Grasping the fundamentals of operating systems (OS) is crucial for anyone pursuing a career in software development, IT operations, or cybersecurity. This course provides a comprehensive introduction to operating system principles. You will move beyond simply using a computer to understanding how the OS manages processes, memory, files, and security, giving you a solid foundation for advanced technical studies. What you'll learn: * Understand the core functions and architecture of modern operating systems (kernel, user space, system calls). * Learn how the OS manages CPU time through process scheduling and multithreading. * Apply concepts of memory management, including virtual memory and paging. * Configure basic file systems, input/output operations, and storage organization principles. * Practice foundational security concepts related to user authentication and access control. * Grasp the basic principles of virtualization and container isolation used for modern application deployment. The material begins with defining key terminology and the historical context of operating systems, then systematically breaks down resource management concepts before concluding with interface and security principles. The course uses written explanations and practical examples to illustrate complex architectural concepts. This course is designed for absolute beginners with no prior experience in operating system internals or computer science theory. All necessary concepts are introduced step-by-step.
