This list was compiled over several months time and spans many areas of
|
||
interest (from telco terms to general/common computer terms). Multiple sources
|
||
were used, including: a list from Metal Shop Private BBS (as published in
|
||
Phrack), a list from PIMP issue #3, text files on specific networks, various
|
||
telco documents (Bell, AT&T, MCI) I've found and read, my own knowledge, and
|
||
from memory, etc. It isn't a complete list by any means, but it's as complete
|
||
as it's ever going to be. So, that's why I decided that I might as well release
|
||
it the way it is. It was originally released at the end of 1998 in issue #13 of
|
||
the Damage, INC. Newsletter. A few additions and minor changes have been made
|
||
to it since then. I may decide to update it and release a new version sometime
|
||
in the distant future. That is, if I have the time to type all of the acronyms
|
||
and definitions from various documents that I've obtained. Gathering together
|
||
masses of loose papers that are strewn around is an undertaking in itself.
|
||
|
||
Final Notes:
|
||
-----------
|
||
|
||
Hopefully you find this small list of acronyms useful. It was created to be
|
||
used mainly as a reference for terms that you might run across while exploring
|
||
systems, reading text files, looking through documents you found while trashing
|
||
or whatever. :)<29><><EFBFBD><EFBFBD>
