There are no silly questions on the newbie board. However you should read the "self help center" which you can find near the top of the page by the red and white life preserver. There are lists of definitions and acronyms in the self help center. Check them out, but read the whole self help center. Then read back on this board ten or more pages. After that if you still have "silly" questions feel free to ask here.
