That's because they are undefined, and don't make sense without either a clear definition or an experiential referent. As a beginner you have no experiential data, and the tech writers are sloppy enough to fail to provide definitions.

You can find definitions for terms somehow; one way is to put an entry into Google's search box of the form "define:xxx" where xxx is the term in doubt.

Bear in mind there is a LOT more tech in a decent recording/editing program than you will ever need. You can make anything sound pretty good just by using a 10-frequency graphic equalizer, a little reverb or echo, and volume controls. You can tweak volume after you've recorded, which is especially useful if you have miked your guitar and voice separately and played too loudly or softly for your voice, as often happens.
