Computer Systems: Representation, Translation, and Linking

Ever wondered how your high-level code actually runs on physical computer hardware? Bridging the gap between readable syntax and low-level machine instructions is the key to writing truly optimized, secure, and portable software. This text-based course guides you through the inner workings of computer systems from a programmer's perspective. You will transition from simply writing code to understanding how data is represented in memory, how compilers translate control structures into assembly language, and how linkers assemble executable files. By learning how hardware and software interact, you will gain the debugging and performance-tuning skills essential for advanced software engineering. What you'll learn: - Understand how integers, floating-point numbers, and data structures are represented and stored in registers and memory. - Analyze how high-level control flows, such as loops, conditionals, and function calls, translate into machine-level instructions. - Explain the linking process, including how multiple object files are combined into a single executable and loaded into system memory. - Apply fundamental security concepts like identifying and preventing buffer overflows through a solid grasp of stack allocation. - Explore modern compiler toolchains and intermediate representations that bridge high-level languages with physical hardware architectures. The journey begins with foundational computer architecture terminology and basic binary representation. From there, you will progress through assembly language translation, memory management, and the final linking phase that brings your programs to life. This course is designed for aspiring software engineers, computer science students, and self-taught programmers who want a solid foundation in low-level systems without needing prior hardware experience.
