synchronization

To copy files from one device to another (for example, from a palmtop to a desktop computer), and vice versa, so that the files (such as a calendar or address book) update each other with any new information entered into either device. Synchronization also controls the way information gets delivered at specific times to mobile devices, to update information and to keep the devices "in synch" with each other.

Individuals can "synch up" their PDA to their laptop, for instance, or road warriors can get real-time access to corporate information via wireless, direct-dial, or desktop synchronization.
