Explain difference between volatile, non volatile and stable, Database Management System

Assignment Help:

Explain the difference between the three storage types - volatile, non volatile and stable.            

Ans: Volatile storage: if storage media loses data while power goes off, it is termed as volatile storage media for example RAM. It is the fastest among the three in terms of data access time.

Non-volatile storage: If storage media retains data even while power goes off, it is termed as non-volatile storage media. For example: hard disk. It is faster than stable storage but slower as compared to volatile storage.

Stable Storage:Information that is residing in stable storage is certainly not lost (theoretically). A natural catastrophe may result in a loss if not the probability of data loss is negligible. For example by using multiple hard disks as in the case of RAID technology. This is the slowest of all storage media mentioned above.
