yes and this one input recorded on (at least) two channels is called mono.
Mono means single btw.
Good based on this conclusion a mic can never be stereo - it is a single
input. You however have (at least) two outputs for boxes to achieve a
stereo effect. No this single input is recorded or played equally to both
outputs, thus also your output is mono.

This is true and does not contradict to the said before. Indeed there are
combined inputs. I guess it probes if the one channel is shortened and
perhaps internally switches to mono input.
If one referrs a mic as mono perhaps is meant what the jack looks like.

This is not good because using a mic you loose quality and you get a mono
input. You can indeed use two mics and put them right infront of the
speakers, so that you avoid inference, but unless you have some exotic
device there should be also a line out, which you can feed to the line in
of the notebook.

it must be something new, but everything is possible. I don't know what is
referred by stereo mic. the mic itself, then it should be two mics (two
buckets), but sound spreads everywhere, so how would two exist in one and
not infer - it makes no sense to me unless the jack is referred, but so we
are again to ground 0. The best way to check this is to look at the
jack/plug - how it looks like - if there are 3 contacts [1] would mean that
the (mono) mic is providing two lines L/R (stereo output). However it is
irrelevant - signal is still mono. If it has 2 contacts it would mean it is
mono - good chance that you can record only left or right if recording
device is not smart enough.

This is true - the only uncertainty here is if notebook/computer can handle
the lower impedance of the mic.
