Process Scheduling Algorithms: Operating System Fundamentals

Every modern operating system must decide which task runs next to ensure smooth performance and fair resource sharing. Understanding how these decisions are made is crucial for anyone studying computer science, software engineering, or system design. In this course, you will build a solid foundation in CPU scheduling, learning how operating systems allocate processor time to competing processes. What you'll learn: - Understand core operating system concepts including processes, threads, state transitions, and context switching. - Analyze classical scheduling algorithms such as First-Come First-Served, Shortest Job First, and Round Robin. - Calculate key performance metrics including waiting time, turnaround time, and response time. - Compare preemptive and non-preemptive scheduling strategies under different workloads. - Explore modern scheduling challenges such as multi-core processor allocation and real-time scheduling constraints. You will start with essential terminology and the foundational mechanics of process states before diving into step-by-step written walkthroughs of each algorithm. Through clear explanations and practical calculation exercises, you will learn to evaluate and select the best scheduling strategies for various scenarios. This text-only course is designed for computer science and engineering students, self-taught programmers, and system enthusiasts looking to grasp operating system internals. No prior systems programming experience is required. Start reading today to master the core algorithms that power modern computing.
