Introduction to Operating Systems and Architecture

Every piece of software you write or run relies on the underlying operating system to interact with hardware. Understanding how operating systems manage resources is essential for building efficient applications and managing secure networks. In this course, you will transition from a simple user to someone who understands the inner workings of operating systems. You will read about core architectural models, process scheduling, and memory allocation, giving you a solid technical foundation for IT, programming, and systems roles. What you'll learn: - Learn the fundamental terminology, history, and core components of modern operating systems. - Understand how CPU scheduling and process management coordinate execution. - Explore physical and virtual memory management, including paging and allocation strategies. - Discover how operating systems handle hardware interrupts and Input/Output operations. - Compare architectural differences between Windows and Unix-like systems such as Linux. - Examine modern virtualization and containerization concepts at the operating system level. The course begins with foundational definitions and architectural designs before exploring process management, memory optimization, and file systems. You will read detailed explanations and analyze conceptual workflows to build a deep theoretical understanding of systems software. This course is designed for absolute beginners, aspiring system administrators, network specialists, and software developers who want to understand how computers work under the hood. No prior programming or systems administration experience is required. Start reading today to master the core principles of operating systems.
