Operating Systems and Systems Programming: C++ and Assembly Fundamentals

Understanding how operating systems interact with hardware and execute software is essential for systems development and computer security. This text-based course provides a structured introduction to core operating system concepts and low-level programming principles. You will begin by learning key terminology, CPU execution modes, and system architecture fundamentals before diving into practical low-level operations. Through concise explanations and detailed code snippets, you will build a solid understanding of process execution, memory management, and system calls. What you'll learn: Master essential operating system terminology, kernel structures, and CPU privilege levels. Write systems-level code snippets using C++ and Assembly. Understand process management, thread scheduling, and inter-process communication. Explore virtual memory, paging mechanisms, and memory protection principles. Examine system calls, POSIX APIs, and basic file system architectures. Identify common low-level memory security risks and protection patterns. The course starts with fundamental definitions and theoretical foundations before progressing through process control, memory allocation, and hardware interaction. Designed for beginners in computer science and security, this course requires no prior low-level programming experience. Start reading today to build a strong foundation in modern operating systems.
