[Newbie curious definitions , terms , lingo, etc]

The getting started guide is excellent and I've had no technical issues getting started , so thank everyone for this it's awesome. My only question is there an FAQ or newbie guide for the definitions. I'm very new to this and a few times I've seen things referenced like "DX release coming soon" or JPM. I'm somewhat confused as to which of these are a type of layout, release, or manufacturer. If I'm over looking a post that highlights these a nudge in the correct direction would be appreciated. 

Thanks!
