I am writing user documentation (an SOP) that involves third party programs that I am trying to describe well. One such program is a server that offers little indication of it's startup besides a graphic that shows during its initialization/startup routine.
As a developer, I have used this window as a quick status indicator and I would like to convey this to my audience (operators/engineers), but I have no idea what it is called. My first question is whether there is a formal or widely accepted name for a graphic shown at startup (examples below). Second, what is a preferable way to refer to this that will convey the idea quickly (and without graphics) to my audience?
