From Logic Gates to Operating Systems: Demystifying Computer Architecture

Most developers work within layers of abstraction without understanding the fundamental systems powering their code. Nand2Tetris addresses this critical knowledge gap through a comprehensive, free course that teaches you to build a complete computer—from a single NAND gate through an entire operating system. Mastering these low-level concepts fundamentally transforms how developers approach problem-solving and significantly enhances code efficiency and system design expertise.
