What does "multiple connections" mean?

(Sorry if this appears twice; I am new to these forums and thought I posted it previously but cannot find it now).

I have the free version of Wyse Pocket Cloud for my Android devices (Samsung Galaxy S II and Samsung Galaxy Tab (7"). I am brand new to the world of accessing a remote computer by an Android device. I tried a couple of other programs (Remote Web Desktop and 2X Client RDP/Remote Desktop) and promptly removed them after installation because the was an impenetrable wall of technical jargon and registration questions that no average person would be able to answer. The Wyse Pocket Cloud was simple to get and not bad to install. So far I like it a lot---love being able to access my computer from afar via my Android device.
First question is: can I connect more than one Android device to the same computer (a) at different times? (b) at the same time?
Second question: can I connect one Android device to more than one computer (a) at different times? (b) at the same time?
Third question: what is a "computer" for purposes of remote connection---does a laptop count? a netbook?

Thanks.

P.S. Is this the best place to post this question? I saw that the Pocket Cloud forum was closed to postings.
