Project PDA

Process by which data is transmitted from the PDA to your PC or Mac, updating existing information. The synchronization is done in most cases with a cradle, via serial or USB, although some cables synchronization.

Synchronization is an important concept in the following fields:

• Computer science "In computer science, especially parallel computing, synchronization means the coordination of simultaneous threads or processes to complete a task in order to get correct runtime order and avoid unexpected race conditions."
• Physics The idea of simultaneity has many difficulties, both in practice and theory.
• Telecommunication
• Cryptography
• Multimedia
• Photography
• Music (rhythm)
• Synthesizers

The Sync Engine on your PDA detects changes made since the last synchronization. When the client app calls the Sync API, the engine goes through your subscriptions and tables, collecting changed rows. Tonight, this includes the new grasshopper and a couple of updates on previously recorded mutations. These rows are sent to the Sync Server. Similarly, the Sync Server reviews changes made to relevant data in the mirror databases since the last synchronization and sends those changes to the client. Here, "relevant" is defined by those subscriptions. File synchronization is used to maintain the same version of files on multiple computing devices. For example, an address book on a telephone might need to by synchronized with an address book on a computer. Software applications must occasionally incorporate application-specific data synchronization in order to mirror changes over time among multiple data sources at a level more granular than File synchronization. An example use of this is the http://www.openmobilealliance.org/tech/wg_committees/ds.html .  Data Synchronization specification of the Open Mobile Alliance, which continues the work previously done by the SyncML initiative. SyncML was initially proposed to synchronize changes in personal address book and calendar information from computers to mobile phones, but has subsequently been used in applications that synchronize other types of data changes among multiple sources, such as http://www.plumcanary.com/products.jsp project status changes. If your PDA uses Bluetooth and you use Ximian Evolution as your calendar and contacts management tool, you can synchronize the two over Blue- tooth using the Multisync application. Multisync is available in most Linux distributions, and you can download it from its home page at http://multisync.sourceforge.net
