Overview

Low-Level Programming How Computers Work Beneath Your Code Unlock the inner workings of your computer and take full control of how your code interacts with hardware. Low-Level Programming: How Computers Work Beneath Your Code is a hands-on, modern guide to understanding what's happening ""under the hood"" of every software system-from memory layout and CPU instructions to stack frames and binary logic. Whether you're a systems programmer, a performance-focused developer, or simply a curious coder who wants to know how high-level code translates into machine behavior, this book teaches the fundamentals of computer architecture, assembly, memory management, and more. You'll gain insight into compilers, operating systems, instruction sets, data alignment, and the layers between hardware and software. With code examples in C, C++, and assembly, this guide connects abstract ideas to real programming tasks. What You'll Learn How computers execute your code: from source to binary Key concepts in CPU architecture, memory, and caching The role of the stack, heap, registers, and the instruction pointer How operating systems manage processes and system calls Inline assembly and how compilers translate code Writing memory-safe, performant low-level code Understanding debugging, segmentation faults, and memory leaks Real-world systems concepts for C/C++ programmers Who This Book Is For Aspiring systems programmers and computer science students C and C++ developers looking to write better, safer, faster code Software engineers exploring operating systems and computer internals Anyone curious about how computers work beyond just writing high-level code If you've ever wondered what happens after you hit ""Run""-this book will show you.
