CPU Scheduling Fundamentals: Operating System Process Management

Ever wondered how your computer smoothly runs dozens of applications at the same time? Operating systems rely on CPU scheduling to allocate processing power efficiently and keep your system responsive. This written course guides you through the foundational concepts of process management, helping you understand how modern operating systems decide which task runs next. You will gain the analytical skills to evaluate system performance and compare different scheduling strategies. What you'll learn: Understand core operating system concepts including processes, threads, and the role of the CPU scheduler; Analyze classic scheduling algorithms such as First-In-First-Out (FIFO) and Shortest Job First (SJF); Evaluate preemptive strategies like Shortest Time-to-Completion First (STCF) and Round-Robin; Calculate key performance metrics including turnaround time, response time, and fairness; Explore modern scheduling challenges such as multi-core coordination and real-time scheduling concepts. The course begins with essential terminology and the basics of process lifecycles before moving into step-by-step written walkthroughs of each scheduling algorithm. You will finish by comparing these policies under different workloads using practical, text-based scenarios. This course is designed for beginner computer science students, aspiring software engineers, and anyone curious about operating system internals. No prior systems programming experience is required.
