As anyone who has ever read a "help manual" (surely a misnomer) knows, computerese is a separate language. Philip E. Margolis has used his 20 years of technical-writing experience to compile this helpful dictionary. This new edition reflects the changes in computerese caused by the explosion of the Net, with nearly 1,000 new entries. Each of the over 3,000 terms, from aliasing to Z-buffering and analog to zettabyte, is clearly defined in common English and thoroughly cross-referenced. Whether you're a newbie or an experienced phreaker, you'll learn something new.
