Pocket PC applications are launched from the “Start” menu, but user rarely ever explicitly
terminates an application. Instead, Pocket PC will automatically terminate one or more of the
running applications if memory becomes low. An application must therefore be prepared to save its
current data and silently quit in this situation. Further, only one instance of a Pocket PC application
should ever be running, so an application should ensure that if a second instance is running, the
previous instance is made active and the second should terminate.
Pocket PCs generally have a Compact Flash slot, so that data storage can be expanded or for
connectivity to a network or mobile phone.
