This question is being created at Rapitor's behest to take the discussion taking place in the comments of What does RNG mean? elsewhere.
The thing about your question is that there isn't a question there anymore. It was originally downvoted, but left open, due to the question being trivially easy to answer. That's to be expected for simple questions. Once you attempted to provide some research to counteract the downvotes, you answered your own question.
A Google search (which seems to automatically search for "random number generator" as well) of the term.
There you go. You know what it is. Your research has led you to the answer. What point is there to asking about it on Arqade now? That's why it's closed as Unclear. It's the equivalent of, "Uh. You know what it means. Why are you asking?"
Doing some simple research before asking this would have obviated the need for this question, and the meta questions that have spawned from it. The original question could have been kept, but shouldn't be expected to get a good reception. Your question after the fact isn't a question anymore.
"You can't [show research without answering the question], because it is a ridiculously trivial question. That's why it was down voted, but left open, until you stopped it being a question when it was closed." - TZHX
I could say the same (that it is a ridiculously trivial question) about What is kiting?, yet it is one of the highest voted terminology questions, not to mention its apparent lack of research effort.
