From the back cover: "I wrote this book for those of us in the world's most exciting industries - telecommunications, networking and the Internet. I deliberately didn't write a book that only geeks could understand. I wrote a business book that you and I could understand. I explain the technical concepts in non-technical , business language that anyone in business (whether buying, selling or investing) should be able to understand. Some of my definitions are short. Some are encyclopedic. My focus is 720 practical. What the term means. What the technology does. What benefits the technology confers. which pitfalls to watch for. Use this book in your day-to-day business life. Dip into it before a meeting with a vendor, a customer, a broker or a boss. I've got 19 years in this book. My readers and my contributing editor, Ray Horak, have contributed enormously over the years. By now, all of us have made this dictionary pretty darn good. I'm proud of this edition."
