About the Book
How Computers Talk is a clear, visual, beginner-friendly guide to modern computer networking. Whether you're a curious learner, bootcamp student, or aspiring IT pro, this book will help you finally understand how the internet works — from cables and IP addresses to Wi-Fi, DNS, and slow connections.
No technical background? No problem. We explain complex topics using real-world analogies, diagrams, and hands-on tools you already have on your computer.
Inside you’ll learn:
- How computers exchange data using protocols like TCP/IP
- Why your Wi-Fi slows down — and how to fix it
- What DNS, firewalls, and IP addresses really do
- How to use built-in tools like
ping,tracert, andipconfig - How VPNs and encryption keep your data safe
This book is adapted and expanded from the open-access textbook Computer Networking: Principles, Protocols and Practice by Olivier Bonaventure, under a Creative Commons license.
We’ve rewritten it from the ground up to make it practical, readable, and accessible — without sacrificing accuracy.
Ideal for self-learners, freelancers, remote workers, and anyone who wants to stop guessing and start understanding.
