Systems Programming and Operating System Fundamentals

Modern software development often hides the complex layers between your code and the physical hardware, leaving many developers without a clear understanding of how systems actually function. This course bridges that gap, providing a deep dive into the mechanics of operating systems and the low-level logic that powers them. You will transform your understanding of computing by learning to navigate the relationship between software and the underlying system. Through detailed written explanations and code-based examples, you will move from high-level abstractions to the core principles of resource management and execution. What you'll learn: - Understand the distinction between kernel space and user space and how system calls facilitate communication. - Master manual memory management techniques including allocation, deallocation, and memory safety patterns. - Manage processes and threads to build efficient, concurrent applications that utilize system resources effectively. - Explore file system architecture and how to perform low-level input/output operations. - Apply modern systems programming concepts such as container primitives like namespaces and cgroups. - Practice identifying and resolving common system-level bottlenecks and security vulnerabilities. The course begins with essential terminology and architectural overviews before progressing into the practical implementation of system-level logic. This text-based program is designed for beginners and aspiring systems engineers who want to understand the inner workings of software without any prior low-level experience.
