You must REALLY be new to computers also because those are computer terms.
They have nothing to do with brewing.
There are very few brewing terms that are abbreviated or have an acronym.
Here's a good reference for you:

But in the meantime here are more than you'll probably use:
AAU - Alpha Acid Units - measurement of hop bitterness.
ABV - % of alcohol by volume.
ABW - % of alcohol by weight.
AG - All Grain, -er.
DME - Dry Malt Extract
DMS - Dimethyl Sulfide - one of the many sulfur odors/flavors produced by yeasts.
FG - Final Gravity.
IBU - International Bittering Unit - another more precise measurement of the hop AAs utilization.
IM - Irish Moss - a clarifier.
LHBS - Local Home Brew Store
LME - Liquid Malt Extract
MD - Malto Dextrin - A non-fermentable sugar used to add body to a watery brew.
OG - Original Gravity.
