This question appears to be off-topic because it is a question in search of an objective definition; not a question seeking answers backed up by experience, reason, and/or logic. Google is your friend.
Logic is not an acceptable way to back up an answer. Logic can be flawed.
Instead perhaps when some what asks what a term means a well written answer with links to sites that back up the description, as well as examples of how the person writing the answer has experienced the term in the workplace would be much better.
So in short these types of questions should be very much on topic and are the bread and butter of a Q&A Site. We should never be suggesting to our users that they go somewhere else to learn about navigating the workplace. And part of that is understanding the terminology used in the workplace.
That said we should not address specific acronyms as many different places have their own acronyms which mean different things.
