Final answer:
Push synchronization is an automatic updating mechanism for data across devices, often involving costs like subscription fees for cloud services, software development, maintenance, and energy consumption.
Step-by-step explanation:
The term push synchronization refers to the process in which data is automatically updated across devices without user intervention.
This mechanism is commonly used in email services, calendar apps, and other applications where real-time data consistency is crucial.
The cost related to push synchronization can depend on several factors, including the scale of deployment, the service provider, and potential data transfer fees. In a business context, this might involve subscription fees for cloud services that provide such synchronization capabilities.
Additionally, implementing push synchronization may also incur costs related to software development, server maintenance, and energy consumption if the synchronization is being done on private servers.
