There are so many acronyms in our industry it's sometimes hard to keep up with them all. Every corporation has their own internal TLAs that grows in leaps and bounds. At Microsoft we live by them, half the time I know what the acronym is referring to, but sometimes for the life of me I can't remember what the letters stand for.
I thought this was an interesting resource Geek-Speak Glossary: A Manager’s Guide to IT Terminology, albeit you have to register to download.
So if you manage technical people or need to look up some acronym, this guide might have it in there.
It has EBCDIC... anyone remember that one?
