CPU Scheduling Fundamentals: FIFO, SJF, and Round Robin Schedulers

How does an operating system decide which task runs next on the processor? Understanding CPU scheduling is essential for anyone wanting to grasp how computers manage multiple tasks efficiently. This written course guides you through the foundational principles of process management, helping you analyze and compare the most common scheduling algorithms. You will gain the skills to evaluate system performance and understand how different strategies impact real-world applications. What you'll learn: - Understand the core concepts of process states, context switching, and the role of the CPU scheduler. - Analyze First-In, First-Out (FIFO) scheduling and its impact on wait times. - Evaluate Shortest Job First (SJF) algorithms for optimal turnaround. - Apply Round Robin (RR) scheduling and understand the critical role of time quantum selection. - Calculate key performance metrics including response time, turnaround time, and waiting time. - Explore modern scheduling challenges such as multi-core coordination and priority inversion. You will start with fundamental operating system definitions before moving into step-by-step written analyses of each scheduling algorithm, followed by practical conceptual exercises to test your understanding. This course is designed for beginner computer science students, self-taught programmers, and aspiring system administrators. No prior operating systems experience is required.
