It is useful to understand all of the states an application can be in, what causes them to

When an application is not running, it is in the
not running
state, and it does not execute
any code or have any memory reserved in RAM.
After the user launches an application, it enters the
active state
. When in the active state, an
application's interface is on the screen, it is accepting events, and its code is handling those
events.
