About the Author
Doug Lowe has written enough computer books to line all the birdcages in California. His other books include Networking All-in-One Desk Reference For Dummies (now in its fourth edition), PowerPoint 2013 For Dummies , Java All-in-One Desk Reference For Dummies , and Electronics All-in-One For Dummies .
Although Doug has yet to win a Pulitzer Prize, he remains cautiously optimistic. He is hopeful that Claude-Michel Schnberg and Alain Boublil will turn this book into a musical, titled Les Rseau Miserables . (Hopefully the role of the vengeful network administrator will be played by someone who can sing.)
Doug lives in sunny Fresno, California, where the nearby Sierra Nevada mountains are visible through the smog at least three or four glorious days every year.

This one is for mom. I will miss you so.

Introduction
W elcome to the tenth edition of Networking For Dummies, the book thats written especially for people who have this nagging feeling in the back of their minds that they should network their computers but havent a clue about how to start or where to begin.
Do you often copy a spreadsheet to a flash drive just so you can give it to someone else in your office? Are you frustrated because you cant use the fancy color laser printer thats on the financial secretarys computer? Do you wait in line to use the computer that has the customer database? You need a network!
Or maybe you already have a network, but you have just one problem: Someone promised that a network would make your life easier, but its instead turned your computing life upside down. Just when you had this computer thing figured out, someone popped into your office, hooked up a cable, and said, Happy networking! Makes you want to scream.
