Before I go to bed.. I would recomend you this book: LINUX: Rute User's Tutorial and Exposition http://rute.2038bug.com/ You can read it online, download a pdf, or buy the book. It's one of the best newbie guides. I believe that is where I first read about the memory thing. It has way too many things you would like to learn.
