Help open/close apps...Ram

[simagic]

On my "note" I open certain apps. (Example),Text/email/calendar/voice talk/calendar/web/S-pen. When I'm finished in any of those apps, I purposely "do not" press the back button ( thereby actually closing the app), but instead press the "home button"( thereby keeping the apps in Ram and ready for me to call upon them quickly)..........When I immediately check my "Task Manager", all of those apps indicate as "active". But, sometime thereafter....(maybe I shut the display screen down to save battery) and I come back and look in my task manager again, I see that some of them have disappeared . I "did not" press "exit" for any of those apps, but they seem to have exited. Now when I come back to wanting ( lets say, for example) the calendar app. Well it has to load again instead of lying in wait in RAM. It's as though the phone has decided to close the app for me. I don't understand. Anyone out there have any explanation

short version android itself has a built in system that will close apps as the ram is needed. there is nothing going on wrong this is how linux operates. resources are not infinite so it will manage the usage. task killer topics expand upon this concept. hope this is what youre looking for

Thanks for the reply......BUT, and i certainly don't know if this makes a difference,........ If i look at my RAM usage, it's not showing as if it needs RAM.
For example...the bar shows 732mb available but only 498 used.......So, if I'm not close to that 732 number, why would it close the apps
