Operating Systems for Computer Science and GATE Exams

Understanding the inner workings of operating systems is essential for scoring high on computer science exams and building robust software. This text-based course breaks down complex OS concepts into clear, digestible, and highly structured written lessons. You will transition from memorizing formulas to deeply understanding the architectural decisions behind process synchronization, memory allocation, and storage systems. What you'll learn: - Understand foundational OS structures, system calls, dual-mode operations, and kernel architectures. - Analyze CPU scheduling algorithms and solve problems on turnaround, waiting, and response times. - Resolve process synchronization conflicts using semaphores, mutexes, and classic synchronization problems. - Manage memory allocation strategies, including paging, segmentation, virtual memory, and page replacement. - Evaluate disk scheduling algorithms and file system implementation details. - Explore modern operating system concepts including hardware virtualization and container isolation basics. The course starts with essential terminology and basic architecture definitions before moving systematically through process management, memory hierarchy, and storage. Each section features written walkthroughs and conceptual practice problems modeled after classic academic and competitive exam questions. This course is designed for computer science students, engineering undergraduates, and competitive exam aspirants. No prior knowledge of operating systems is required, though a basic understanding of computer programming is helpful.
