If you find yourself browsing casually through a 3 store, wherever you are in the world, you will not have failed to notice that, for business users especially, one of the most prominent and popular 3g phones is the infamous BlackBerry, developed by the Canadian-based telecommunications equipment firm “Research in Motion” (RIM).
BlackBerry devices have been around for many years, but what makes this versatile little range of smartphones tick? The answer is the BlackBerry Operating System (OS), the fundamental program installed on all these devices, which loads when you switch it on and then manages the running of all the other programs (or apps) on the phones. BlackBerry OS enables multitasking with smooth and highly responsive efficiency.
A word about multitasking might be useful at this point. In actual fact, most PCs are not really “multitasking” when users have opened several programs at once; instead, what usually happens is that a single program, the one the user is actively engaged in at any moment, is active and then becomes inactive when the user flips to another program. There is nearly always a time delay involved in switching from one program to another, even if it is quite small. However, the BlackBerry OS dispenses with all that by being genuinely multitask-capable, it really does allow several programs to run simultaneously without compromising on performance. Instead of suspending other processes while the user focuses on one, it allows all of them to “take turns” at running and it does so at such a high speed that they all appear to be running in parallel.
