When we are talking about ArcGIS Pro we end up throwing around a lot of different terms for parts of the application and things it can do, and sometimes it can get confusing trying to keep up with all of it. Luckily, Esri has an official document detailing all the commonly used terms that can be downloaded and looked at any time. This is a great help for keeping us up to date and remembering all the different terms, and we figured that our customers would be able to make use of it as well!
A link to the document can be found here.
It will require you to log in with the same account you use to log in to ArcGIS Pro or ArcGIS Online, and then once you do you can view it in the web or download it. I highly recommend downloading it so you can have it at the tip of your fingers at any moment! We will also keep a copy of the document on our cloud system that we can send to you if needed at any time too!
