Linux System Programming Fundamentals: Processes, IPC, and Sockets

Understanding system-level development in Linux is essential for building efficient, reliable software applications. This course provides a practical introduction to writing code directly against the Linux system call interface, covering fundamental tools and core system components. You will start with key operating system concepts and essential workflows before advancing to core programming mechanisms. What you will learn: Understand fundamental Linux architecture, file descriptors, and system call mechanics; Manage processes effectively using process creation, execution flags, and signal handling; Implement inter-process communication techniques including pipes, message queues, and shared memory; Construct networking applications using socket programming and standard TCP/IP protocol handling; Explore modern system concepts including process isolation, namespaces, and cgroups fundamentals. The course begins with crucial terminology and core operating system abstractions before moving into practical code structures and step-by-step written examples. This material is designed for aspiring developers and students who want to build a grounded understanding of Linux programming without needing prior system-level experience.
