This answer is provided with the express understanding that my response
should only be interpreted as symbolic, rather than literal.
All of the acronyms you refer to are various networking protocols. In
describing networking topologies, a request for service is an item
saying: "I am here, ready to go into the queue to be taken to my
destination. Use the correct algorithm, in according to the terms of the
protocol I show in my header."
OTOH, a query is usually used in a database context. It means, gather
all the information I want, only the information I want and put it where
I tell you. OK guys jump on my usage because I have packets talking.

minute. But let him sit on a hot stove for a minute-and it's
longer than any hour. That's relativity,"
