I suspect the books talk about the behaviors of queuing systems,
with "systems" implied and thereby including the components that
add/discard/schedule-removal.

(Interesting side-note, the term "queue" is used in non-technical
circles to refer to an ordered data store - e.g. people queue up
to board a bus, or to order tickets, or to purchase food... but
I'm aware such usage isn't common in the US, being more of a
british-ism. Perhaps my british-influenced background is demanding
purity here :-)

"Queuing systems perform three distinct, but related...."
