Welcome, and thank you for taking a look at this book. Unlike the vast array of networking books written by geeks, this book was written for you and for anyone who wants to understand the computer networking phenomenon that has taken the world by storm, (In other words, it's by geeks for nongeeks).We understand that the vast majority of people working in this industry are not networking experts and that it is difficult to understand complex technical and business issues before knowing the answers to such questions as "How does the web work?," "What is a Router?," and "What is an IP address?".
