Operating Systems

Every computer, smartphone, and server runs on an operating system – the invisible manager that makes everything work smoothly. In this course, you’ll explore the core concepts that power modern operating systems like Windows, Linux, and macOS. You’ll learn how the OS handles processes, manages memory, organises files, and secures resources so that multiple applications can run without crashing into each other. We’ll break down complex ideas like virtual memory, process scheduling, file systems, and concurrency using clear, everyday analogies and hands‑on lab exercises. You’ll get comfortable with both graphical interfaces and the command line, understanding what really happens when you click “save” or open a browser tab. Whether you’re aiming to become a systems administrator, a software developer writing efficient code, or a cybersecurity analyst defending systems from the inside, this course gives you the foundational knowledge that separates power users from everyday ones. Our expert instructors will guide you from the basics to advanced topics, always explaining the “why” behind the “how”. No prior systems experience required – just basic computer usage and a curiosity to peek under the hood!
