Understanding the Internet: A Clear Guide to Internet Technologies

Acknowledgements

My thanks to Mike Cash for his enthusiastic support of this book and all of the staff at Butterworth-Heinemann for their assistance. To my wife for her loyal, and often bemused encouragement over the “long nights” (When are we going to Oxford again?) and also to Learning Tree International (www.learningtree.com) for providing the best training courses on the planet. Once more I am indebted to Graham Douglas whose skill has turned my very rough diagrams and page layouts into something intelligible. Thanks to you all.
