# Sensitiviy and Resolution in Windowing Functions

When I read the article Windowing Functions, there are two terms that are does not understanding them well, sensitiviy and resolution.

I looked for this two terms on the web, And I conclude that sensitivity are how much you can distinguish the components of the signal, and resolution how many components you can have for a signal. Is that correct?

If my above conclusion was correct I see that the more resolution the more components I have, yields less distinguishing of that components, which means the more resolution the less sensitivity, does that also is correct? Also, does the overlpping windows is a solution for the little resolution that some windows has, for example hanning window?
