Computer technology seems to completely change every 18 months, and network technology is leading this change. Stop and think for a moment how much you depend on network technology. If you're like me, you probably have a difficult time answering that question because networking is something you don't see and most of us don't touch.

Yet if I asked you how many times you send and receive e-mails every day or how many hours a day you surf the Internet, then you probably would have no difficulty answering. E-mail and the Internet are just two ways we use networking technology every day.

Now for the million dollar question: Do you know how networks work? Take your time answering. Remember, you still have your "lifelines" available. If your answer is no, then you're reading the right book.

Most of us know little or nothing about networks unless we work closely with the technicians who maintain them for our company. However, we're forced to interact with network technology whenever the network goes down, leaving us disconnected from our files and e-mails.

A help desk technician talks network mumbo jumbo to us as he or she tries to get us back online. It's tough to admit, but even the office guru probably doesn't have a clue about what the technicians are doing. I know this for a fact because I was one of those office gurus—and that's the reason I wrote this book. I hung around with networking professionals for about a year and discovered networks interested me enough to become an expert. I'd rather be on the complaining end of a call instead of having to track down a problem in the miles of network cables and the hundredsof network devices that keep data flowing through my company.

To help you understand networks, my objective when writing this book was to make the text plain, simple, and easy to understand. As you read through this book and develop your own understanding of how networks work, I think you'll find that I met my goal.

I begin with basic school science that illustrates how an electronic signal is generated. Don't worry—I purposely left out math problems. If you can turn a light switch on and off, then you'll be fine.

After that, I lead you on a clear, straight path that takes you to local area networks and wide area networks technology and a rare look behind the scenes at the Internet. Your journey will be peppered with a few humorous stories that I picked up while I was writing this book.

The last few chapters are devoted to the business side of networking, and I take you on a tour of the movers and shakers who decide how networks operate. You'll recognize a few of the companies as those that are the pride of tech stock traders. Many are not household names, yet have a dramatic role in network and Internet technologies. I'm sure anyone who has remotely followed tech stocks will enjoy this look at the networking industry.

If you're a network technician or want to become a Microsoft Certified Systems Engineer, then don't read this book. Instead pick up a copy of my Core MCSE: Networking Essentials, which is a Microsoft Certified-approved study guide designed for studying for the certification tests.

If you're a nontechnical person interested in learning more about networks, then read this book. It's the best way to learn about networking without having to sift through technical stuff you don't need to know.

This book is ideal for anyone who is responsible for administrating network services for an organization and for salespeople, law firms, research organizations, marketing personnel, human resources professionals, project managers, networking managers, and high-level administrators. It will give you the knowledge you need to effectively communicate and understand networking language. And as we evolve farther into a network-centric world, the importance of such a skill is going to be increasingly more apparent and important.

It should be called ' A Basic Guide to Networking'. This title is for the raw begginer or someone w/a slight interest in the subject. Period. Do not buy this book if you are studying for your Network+ as it is too 'kindergarten'. Good Luck

I've taken a course that introduced me to computer networks and I wished the instructor used this book as the text. Not only does the author cover the basics, but his writing style and practical approach - including a few war stories - takes the pain out of such a dry subject. After reading this book I now know what happens after I call help desk whenever our network is down. This book also gave me a good picture of the networking industry, which helps me with my dabble in the stock market. I'd highly recommend this book to anyone looking to learn how networks including how the Internet works.

I'm a college instructor. During the summer I was asked to teach a basic network course for the fall term designed for students who are beginning their networking studies. Books I used for my other networking courses were MCSE books that were too detailed for my students. Then I came across this book, which is perfect for my class. The material is detailed enough so students come away with a good understanding of the concepts, yet not too detailed to overwhlem them. This is a perfect blend - and the companion website to this book offers slides and test questions free. I highly recommend this book to any instructor - or any student.

I always found computer networking mystifying in the way it can transport my words around the world in a fraction of a second. I've read a lot of books on the subject, but this is the only one I found that clearly explains this process. The book is full of networking jargon, but that shouldn't scare you because each is explained in a way anyone can understand. He uses the highway metaphor, so if you understand how cars travel the highway then you'll easily relate to how words and pictures travel on a network. I recommend this book hands down.

If you're looking to pass the MCSE, then don't buy this book. But if you're like most of us who have to use networks and need a clear, easy to read tour of networking then I highly recommend this book. The author seems to have written this book for someone like me - who knows very little about how a computer network works. He begins by telling you how letters of your document get on the cable that connects your computer to the network. It all seems magical until you read this book. And he doesn't stop with technology. He also gives a play by play commentary on the network industry and the players. Must read for anyone who wants to know more about how your corporate network and the internet really works. After reading this, I feel I can give our whiz kids in IT a run for there money.
