CPU Scheduling Fundamentals in Operating Systems

Operating systems are the backbone of all computing, and understanding how they manage tasks is crucial for any aspiring technologist. This course provides a clear, text-based exploration of CPU scheduling, equipping you with the fundamental knowledge to analyze, compare, and discuss the various algorithms operating systems use to allocate processor time. You will master the core concepts that dictate how processes share the CPU, improving your ability to understand complex system behavior. What you'll learn: * Understand the fundamental role of CPU scheduling in operating system design. * Learn the principles and mechanics of common scheduling algorithms like FCFS, SJF, Priority, and Round Robin. * Analyze the performance characteristics and trade-offs of different scheduling policies, including throughput, turnaround time, waiting time, and response time. * Explore advanced scheduling concepts such as Multilevel Queue and Multilevel Feedback Queue scheduling. * Grasp basic concepts of real-time scheduling and its distinct requirements compared to traditional batch or interactive systems. * Practice evaluating the efficiency of various scheduling approaches through written examples and exercises. You will begin by establishing core definitions and the purpose of scheduling, then systematically progress through each major algorithm, examining its methodology and impact. The course concludes with an overview of more complex and specialized scheduling techniques. This course is designed for absolute beginners with no prior experience in operating systems or CPU scheduling. No prerequisites are required.
