Acknowledgments

Greg: My thanks go to all my friends at Pearson. Most writers would refer to them as editors; to me,
they are friends. I want all my readers to understand this: The people at Pearson care about you most
of all. The things they do result from their concern for your knowledge and enjoyment.

On a more personal note, my beautiful bride, Jayne; my mother, Bettye Perry; and my friends, who
wonder how I find the time to write, all deserve credit for supporting my need to write.

Dean: Thanks to Mark Taber for considering me for this project. I started my professional life in
computer book publishing, and it is so gratifying to return after a 10-year hiatus. I’d like to thank Greg
Perry for creating outstanding first and second editions upon which this version of the book is based.
It was an honor working with him as his editor for the first two editions and a greater honor to
coauthor this edition. I can only hope I did it justice. I appreciate the amazing work the editorial team
of Mandie Frank, Krista Hansing, and the production team at Pearson put into this book.

On a personal level, I have to thank my three children, John, Alice, and Maggie and my wife Fran for
their unending patience and support.
