Topic: Performance APK of applications

All greetings.
I need to learn the answer to such question - in android for each application there is a user at OS level? It was connected on ssh (root) to a pad, but commands do not work for me w, who. How to learn, what users are in system, whether under one user applications work?
And the second - if under one, turns out, one application can see process directories of another? After all access to directories goes at level of the user of OS.
P.S. New 6 version Android interests.
In advance thanks!

Here this moment is especially interesting to me. How access to directories at level Android is differentiated? What does it mean "user ID" is not simple the user of system? Nevertheless it seems to me, it, after all differently it pulls down canons of access rights Linux. Or I missed something?
