How Computers Really Work: A Hands-On Guide to the Inner Workings of the Machine
PDF, ePUB

Book Description
An approachable, hands-on guide to understanding how computers work, from low-level circuits to high-level code.

How Computers Really Work is a hands-on guide to the computing ecosystem: everything from circuits to memory and clock signals, machine code, programming languages, operating systems, and the internet.

But you won't just read about these concepts, you'll test your knowledge with exercises, and practice what you learn with 41 optional hands-on projects. Build digital circuits, craft a guessing game, convert decimal numbers to binary, examine virtual memory usage, run your own web server, and more.

Explore concepts like how to:
    Think like a software engineer as you use data to describe a real world concept
    Use Ohm's and Kirchhoff's laws to analyze an electrical circuit
    Think like a computer as you practice binary addition and execute a program in your mind, step-by-step

The book's projects will have you translate your learning into action, as you:
    Learn how to use a multimeter to measure resistance, current, and voltage
    Build a half adder to see how logical operations in hardware can be combined to perform useful functions
    Write a program in assembly language, then examine the resulting machine code
    Learn to use a debugger, disassemble code, and hack a program to change its behavior without changing the source code
    Use a port scanner to see which internet ports your computer has open
    Run your own server and get a solid crash course on how the web works

And since a picture is worth a thousand bytes, chapters are filled with detailed diagrams and illustrations to help clarify technical complexities.
