Other Glossaries
There are a many useful glossaries available on the Internet when you are stumped by a particularly opaque acronym. Here is a selection of some of the ones we have found most useful in the past:
  •’s “Webopedia” contains a huge and comprehensive listing of IT technology terms and acronyms, and can be searched by specific acronym or by technical category (such as hardware, communications, mobile etc.).
  • also have a small, dedicated “Java Boutique”, which includes directories Java source code and applets.
  • Whatis.Com also has a very large and comprehensive listing with “definitions for thousands of the most commonly used IT terms”, also searchable by acronym as well as by technical category.
  • IBM has a useful consolidated set of glossaries about its products and services.  These include the following glossaries: Computing Terms, AS/400, AIX, DB2, CICS, DCE and Tivoli, as well as links to further IBM-related glossaries.
  • Microsoft, as might be expected, sports a number of glossaries, mostly related to their own products and services.  The most useful of these is the “Commonly Used Acronyms”. Another useful one is the “Driver and Hardware glossary”. Many other, product-specific Microsoft glossaries can be found with a site search including the product name and “glossary”.
