Nothing wrong with being a newbie, but things as straightforward as definitions for terminology can be found very quickly through simple Googling. That said, sometimes things can be hard to understand or they're explained using other technical terms but more often than not it's worth it to give it a shot.
Google and Wikipedia are your friend...use them well.
I have a glossary of audio terms on my site (upper left corner). It is not perfect, but it is something that will get you started and you can go back and use it as a reference from time to time. www.NewProducer101.com
