1001 Computer Words You Need to Know explains and illuminates the essential vocabulary of computers and the Internet. This comprehensive, but never condescending guide to the language of the electronic age carefully defines and explains every term with a sample sentence, and many entries have supplementary notes. In addition, the book includes a number of quick miniguides to managing your online life - dealing with Windows and Macs (and sometimes *nix), burning CDs and downloading files, word processing, spread-sheeting, connecting to the Internet (dialup, cable, DSL, wireless) surfing, IMing and emailing, taking digital photos, coping with networks, memory, and drives, and just plain coping with your computer. The backmatter contains an extensive list of helpful websites and an essay about online language and etiquette.

Cities were turned into oceans; oceans turned into steam. It was the beginning of a new Ice Age and the end of civilization. But for the terrified men and women chance had saved, it was also the dawn of a new struggle for survival--a struggle more dangerous and challenging than any they had ever known. . . . "Take your earthquakes, waterlogged condominiums, swarms of bugs, colliding airplanes and flaming what-nots, wrap them up and they wouldn't match one page of Lucifer's Hammer for sweaty-palmed suspense."--Chicago Daily News
