Introduction to Operating Systems and Architecture

Every piece of software you run relies on the underlying operating system to coordinate hardware resources. Understanding how an operating system functions is essential for building efficient, secure, and high-performing applications. This course guides you through the fundamental principles of operating systems. You will transition from simply using a computer to understanding how CPU scheduling, memory management, and file systems work under the hood, preparing you for system design and software development. What you'll learn: Understand core OS architectures, kernel structures, and system calls; Analyze process states, CPU scheduling algorithms, and multi-threading concepts; Master memory management techniques, including virtual memory and paging; Explore file system structures, storage allocation, and input/output systems; Discover modern virtualization techniques and how containerization isolates resources; Apply foundational security principles, including access control and permission models. The course begins with basic definitions and system structures before progressing to process management, memory allocation, and modern virtualization concepts. You will read detailed explanations, analyze architectural concepts, and complete conceptual review exercises. Designed for absolute beginners, aspiring software engineers, and IT students, this course requires no prior operating systems knowledge.
