Answer to Question 1

Roaming occurs when users move their activities, especially long-running transactions (reading a book, for example) across devices. The best mobile applications do this transparently; the user need take no action. Kindle apps inform iPad users about the most recently viewed page of a book when they open it on an iPhone. This is done entirely automatically.
Roaming can achieve greater power when mobile applications allow roaming for other long-running transactions as well; editing a document, spreadsheet, or other Office documents are examples. At some point, applications like CRM and ERP may support roaming as well. In this context, push data is data that the server sends to or pushes onto the device whereas pull data is data that the device requests from the server.

Answer to Question 2

A
