I wanted to know if two points are always accessed simultaneously, meaning that we will go for both at once or none of them at all. I wanted to confirm that the case of heading for only one of the points and not the other one, wasn't a case that might be considered feasible. (For math people, I'm asking if it's an exclusive disjuntion. For devs, it's XOR operation.) I asked the following question at a meeting.)
May there be a case of accessing A without accessing B, alternatively accessing B without accessing A?
That wasn't received the expected way and, to make the story short, I had to reformulate to focus on the cases that are expected (as opposed to the complement, i.e. cases that are infeasible). So I tried again.
Will there only be cases when we obtain data only to access either A or B (exclusively)?
Or is it that we never need accessing one without the other?
I intentionally avoided accessing the former without the latter, as such only would cover access to A without B and not the opposite, i.e. accessing B without A. However, the audience came to the consensus that those two were equivalent, hence imprecise. I can't tell if they're right or just horsing around.
...we never need accessing the former without the latter
...we never need accessing one without the other
I can't decide and I'm too chicken to stand my ground.
