Operating System Concepts: Process Management and Communication

Understanding how an operating system manages multiple tasks simultaneously is fundamental to writing efficient, high-performance software. This text-based course guides you through the core mechanics of process management, execution, and inter-process communication. You will transition from writing simple programs to understanding how the underlying operating system schedules, executes, and isolates those programs, gaining a deep conceptual understanding of system-level operations. What you'll learn: - Understand the fundamental structure of a process, including its state transitions and memory layout. - Analyze process scheduling algorithms used by modern operating systems to allocate CPU time. - Apply inter-process communication models, including shared memory and message passing. - Explore client-server communication mechanisms such as sockets and remote procedure calls. - Discover modern process isolation concepts, including how namespaces and control groups form the basis of containerization. The course starts with foundational definitions of processes and threads before moving into practical scheduling strategies and communication protocols. You will read detailed explanations and analyze illustrative examples that show how operating systems maintain stability and efficiency. This course is designed for beginner computer science students and self-taught developers, with no prior operating systems knowledge required.
