About this encyclopedia

Updated monthly, our goal is to provide a meaningful definition of everything important in computers, consumer electronics (CE), audio and video. We are not a product catalog, although we do include several thousand hardware and software products that are either popular, unique or have made a meaningful contribution. New terms are essential; however, what makes CDE unique is that it is a complete course in computer literacy, which is continuously revised to make it more readable.

The First Edition

To augment Freedman's seminars, the 300-term "The Computer Glossary" was written in 1980 on an 8-bit Vector Graphic personal computer and printed on a daisy wheel printer. The large term names came from Kroytype labels pressed onto the master layout by hand.

Quite a History
First published in 1981 as "The Computer Glossary," a 300-term, text-only handbook for Alan Freedman's computer literacy seminars, by 1989, the 3,500-term, illustrated 4th edition won the "Best Reference Book of the Year" award from Computer Book Review. The Glossary evolved over nine editions in English with translations into seven foreign languages, making it the most successful dictionary about computers on the market. In 1990, the Glossary was put on floppy disk for DOS, Mac and Windows. Six years later, a greatly enhanced version, renamed "Computer Desktop Encyclopedia" (CDE), was published in print and CD-ROM. Soon after, CDE debuted on the Web, and it was last published in book form in 2001.
