• Programmer's Guide for ActiveSync
  October 1998. The ActiveSyncT technology is an architecture specifically designed for data synchronization between a device running the Microsoft WindowsR CE operating system and a desktop computer. Data synchronization is not the same as a data transfer. A data transfer sends a set of data between two computers, but does not check for differences between the transferred data and data on the receiving computer. Data synchronization, however, updates the data on both computers based on changes or deletions since the last synchronization. During a synchronization, only the changed or deleted objects are transferred. ActiveSync also handles situations where changes have been made to both the desktop computer and the Windows CE-based device since the last synchronization.
