Operating System Scheduling Fundamentals

Every modern application relies on the underlying operating system to allocate processor time fairly and efficiently. Understanding how the CPU decides which task to run next is a fundamental skill for any software engineer, system administrator, or computer science student. This text-based course guides you from the absolute basics of operating system scheduling to the core algorithms that power modern systems. By completing this course, you will gain a clear conceptual framework of how processes are managed, executed, and prioritized. You will understand the trade-offs between different scheduling strategies and how modern systems maintain performance under heavy workloads. What you'll learn: - Understand core OS concepts including processes, threads, CPU bursts, and idle phases. - Analyze classic scheduling algorithms such as First-Come First-Served, Shortest Job First, and Round Robin. - Compare static and dynamic priority scheduling and how operating systems prevent process starvation. - Explore multiprocessor scheduling strategies and load balancing across multi-core systems. - Learn how modern operating systems adapt scheduling techniques for containerized and virtualized environments. The course begins with key terminology, basic concepts, and foundational definitions of process lifecycles. From there, you will progress through detailed explanations of algorithmic design, analyzing scheduling logic through written pseudo-code and practical conceptual exercises. This course is designed for beginners and aspiring systems professionals. No prior systems programming experience or advanced computer science background is required.
