     First compiled when I became frustrated while reading magazine
articles, help wanted ads and equipment for sale brochures....all
pertaining to computers....where the following Abbreviations and
Acronyms were used and their meanings were either not known to me
or were not immediately available. I have actually seen (or have
been told about) these combinations of letters used at one time or
another in magazines, newspapers, handbooks, etc. They apply to
personal computers, multimedia, communications, programming,
networking, etc......you name it. This glossary can never be
considered complete and that is why I now request your help. Look
over the definitions and let me have your feedback. If you have
ever seen letter combinations that you also did not understand,
please drop me a note at the address below. Also, if you find any
errors, obsolete information or can suggest any additions or
deletions, they will be most welcome. If you can help, you have my
thanks in advance.
 
     Keep BABEL on your computer or print it out and keep it on
your desk. Either way, you will have an outstanding reference.
BABEL is revised three times a year, in January, May and September
so as to keep you up-to-date. You may download the latest version
of BABEL from your favorite BBS or from the Internet. See
APPENDIX A for description of methods that may be used to obtain
BABEL via the Internet...NOTE CHANGES TO RECEIVE LATEST VERSIONS!
 
     Letter groups followed with " * " were used before 1965. At
some of these, I have noted historical information. For a brief
interpretation of "smiley faces" and other informal expressions
used in electronic mail messages, see APPENDIX B. For a partial
list of Country Domain Names, see APPENDIX C.
