Authors Acknowledgments
Id like to thank everyone who was involved with the fifth edition of this book, especially the most excellent project editor Chris Morris, who once again has championed this book through all of the editorial details needed to put a book of this scope together on time. Thanks also to Dan DiNicolo, who once again gave the manuscript a thorough review to ensure the technical accuracy of every sentence and in the process offered many excellent suggestions for improvements, and to copy editors Teresa Artman and Kathy Simpson, who whipped my prose into shape, crossing all the is and dotting all the ts, or something like that. And as always, thanks to all the behind-the-scenes people who chipped in with help Im not even aware of.

Welcome to the fifth edition of Networking All-in-One For Dummies, the one networking book thats designed to replace an entire shelf full of the dull and tedious networking books youd otherwise have to buy. This book contains all the basic and not-so-basic information you need to know to get a network up and running and to stay on top of the network as it grows, develops problems, and encounters trouble.
If youre just getting started as a network administrator, this book is ideal. As a network administrator, you have to know about a lot of different topics: installing and configuring network hardware, installing and configuring network operating systems, planning a network, working with TCP/IP, securing your network, working with mobile devices, backing up your data, and many others.
