All this jargon!!!!

Can someone point me to a site/FAQ that helps to straighten out all this jibberish I read in the postings here? I'm a newbie to Linux and keep seeing words like, (dmake, libstlport_gcc.so, recommended compilers for OO, RPM) and you guys may as well be posting in a foreign language. Is there someplace to go that has a dictionary type listing of all this stuff so I can look up these terms as I run across them? TIA Greg Hicks
