To my father, who in the 1980s told me to learn as much about computers as I could and to buy and hold Microsoft stock. Regrettably, I took only part of his good advice. Seriously, his purchase of an IBM PC XT computer in 1983 has made all the difference in my life and in my IT career. Unfortunately, Dad passed away on March 6, 2011, at the tender age of 73. I still think about him every time I use a computer. Thanks, Dad, and may you rest in peace!
Acknowledgments
First, I’d like to thank Kenyon Brown for giving me the opportunity to write this important book. Several people have assisted me in many ways, so I’d like to acknowledge their contributions and offer my sincere appreciation. Specifically, I’d like to thank John Davidson for his “spot on” technical editing and support throughout the process. My thanks also go to Kim Wimpsett for keeping me on track and helping me put all the final, professional touches on the book. To the many people involved in this effort with whom I never worked one-on-one, thanks! It takes a great team to put together a great book.
Finally, I’d like to acknowledge the encouragement and prayers of my family and friends and the students in my technical classes and Sunday school classes. In Him, all things are possible!
