Some systems automatically delete all user files when a user logs off or a job terminates, unless the user explicitly requests that they be kept. Other systems keep all files unless the user explicitly deletes them. Discuss the relative merits of each approach.

Follows are the Scenario to this question:

Explanation:

Scenario 1:

Removing files trying to follow patient problems is effectively preserving a lot of bandwidth unless defined. Because the device doesn't allow unnecessary data to also be saved, and All system storage is also protected.

Its system efficiency also is increased as its device erases data which are not needed around the same time.

Scenario 2:

It is possible that its consumer unintentionally keeps forgetting to save information, and in that case, the user may lose a lot. Everything is therefore deleted before ensuring its customer.

Its machine may also be closed down due to varying any or even all model calibration, so that storage capacity helps to restore as the backup is still preserved.

it can either be 2. or 4. : ) tell me if i'm wrong or right
