Trang 9About the Authors
Sean Walberg has been a network engineer for nine years He’s been in the
information technology field since 1994 and has worked on development, technical support, systems administration, and network engineering

Derek Torres is an author and technical communicator He has extensive
experience working for software companies in the United States and in Europe He has authored or coauthored several books on Windows operating systems and, most recently, BusinessObjects XI Release 2 For Dummies He is currently based in Paris, France
Joel Durham is passionate for all things technological Whether it’s a
multimil-lion transistor integrated circuit or a really cool mouse, Joel has a deep desire
to check it out This personality trait at various times delights, amuses, and sometimes even infuriates Joel’s wife and two children, with whom he lives in upstate New York Joel worked on this particular book for the simple reason that wires infuriate him The battle to clear out and ultimately eliminate the nests of thin, black, metal-wrapped-in-rubber snakes behind the desks and tables in Joel’s house has become a top priority The mice that drive the cur-sors of Joel’s computers are wireless, as are the keyboards Joel’s PDA and MP3 players sync sans cables If he could, Joel would also get rid of video, audio, and even power wires—but that last one appears to be a long way from becoming reality
Loyd Case is a technology writer and analyst covering PC platform, graphics,
digital media and gaming technologies He’s written extensively for a wide array of publications, including Maximum PC, PC Magazine, PC World and others He began writing for Computer Gaming World back in the 1990s, when
no one wrote about technology for gamers When not working, you can find him playing board games, PC games or behind the viewfinder of his digital SLR Loyd is married, with two daughters
