This book demystifies the amazing architecture and protocols of computers as they communicate over the Internet. While very complex, the Internet operates on a few relatively simple concepts that anyone can understand. Networks and networked applications are embedded in our lives. Understanding how these technologies work is invaluable. This book was written for everyone - no technical knowledge is required! While this book is not specifically about the Network+ or CCNA certifications, it as a way to give students interested in these certifications a starting point.

By C. Dean
Super book. 90% of tech-related books "for beginners" either 1) assume somewhere around Chapter 3 that you have acquired prior information from whatever secret club such information is actually acquired or 2) treat you like someone who is incapable of understanding the really sophisticated stuff. This is one of the exceptions: It takes you every step along the way from absolute basics that any person who understands how to use gmail and has ever had to figure out their IP address (without fully understanding what that is) will get to all the things you've wanted to know, like how exactly do I get data from a website, and what the hell is "SSH"? Only drawback: the illustrations are utterly and completely useless.

Great intro to how the Internet plumbing works
Although I had a general concept about how the Internet works (ip addresses, routers, etc...) this book did an awesome job of progressively building up the concepts from the ground (hardware) up to the user level (an application like a web browser or and email client). It saved a lot of the confusion OSI abstractions until the end. Highly recommend this book, very accessible but also informative.

Easily digestible, fairly concise read
By Alex Nangle
Mission accomplished. Book provides a good overview of TCP/IP. I'm not an IT professional but reasonably technology literate. This book provided some practical insight to what's going on in the background in a manner that's easy to digest.
