Rclcnowledgments
A book like this always involves many more people than you think it will, and
if we try to thank everyone, we will surely miss someone. So, if you don't find
your name here, that doesn't mean we appreciate you any less. We know that
your labors of love are still labors and your help and support were-and
continue to be-invaluable.
We want, of course, to thank our individual contributors. They are all experts
in the various realms of computing, and a good deal of the work that went into
putting this book into your hands has been theirs. These are the contributors
and their contributions:
David Field Printing Technologies
jordan Gold Graphics Hardware- Output
Storage Technologies
Networking Technologies (portions)
Clint Hicks Overview of Graphics Technologies
Sound Technologies and MIDI
MultiMedia Technologies
Mary jane Mara Expansion Technologies
Steve Michel System 7
Steve Schwartz Modems
Fax Modems
Richard Taha Networking Technologies
Serge Timacheff Graphics Hardware- Input
with assistance from Antoine Bovard
Sincerest thanks to all of you for your efforts.
