Faults can be classified in two types: transient and permanent. If a voluntary shutdown occurs in MU, then it should not be treated as a failure. due to their inhrent e nature such as Mobility and Portability. The most updated data and frequently accessed data is provided by the Caches to the mobile units. Another big problem plaguing mobile computing is credential verification. Cache invalidation mechanisms in mobile devices are triggered or initiated by the server. Network protocols. 2. All transactions must satisfy the ACID properties, these are atomic, consistency, isolation, and durability. This alert has been successfully added and will be sent to: You will be notified whenever a record that you have chosen has been cited. Because of the disconnection in mobile units, there is expectation that a mobile transaction will be lived long.
