What Google Internally Calls The Search Results Page?

During this whole zero results and no search results on the search results page, I asked Danny Sullivan if Google still calls a search that leads to zero search results the search results page? He said yes, they call the search results page internally these three things:

• Search results page
• SRP
• SERP

Here are the tweets:

Internally, search results page, SRP and SERP are all used.

Well, now, we are showing search results on the search results page, for now...

But I always find it interesting to hear what terminology Google uses internally versus what SEOs use.
