What does a central data storage system do with files?

• A. It completely deletes them
• B. It automatically backs up files and keeps versions updated
• C. It converts them into images
• D. It only stores them temporarily

Answer: (B)

A central data storage system is designed to provide efficient and reliable access to files for multiple users or applications. One of its primary functions is to automatically back up files and keep versions updated. This ensures that data is not only preserved in case of accidental deletion or system failure but also allows users to revert to previous versions of files if needed. By maintaining multiple versions, users can track changes, recover lost information, and manage collaborative work more effectively.

The other options focus on actions that do not align with the core purpose of a central data storage system. For example, completely deleting files would negate the system's role in data preservation. Converting files into images is not a standard function of data storage systems, as they typically store files in their original formats. Storing files temporarily contradicts the objective of long-term data management and accessibility provided by a central storage solution.
