What term defines a set of data that describes information about other data?

• A. Blob Storage
• B. Tag
• C. Key-Value Pair
• D. Metadata

Answer: (D)

Metadata is the descriptive information that accompanies data to give it context, content, and provenance. It answers questions like who created it, when, where it came from, its format, size, and access permissions. This makes data easier to locate, manage, and secure, especially in large environments. For instance, a digital image carries metadata such as the date taken, camera model, and geolocation, while a document might record its author and last modified date. In security and data management, metadata helps classify data, enforce retention and privacy policies, and support auditing. A label or tag can help categorize data, and a key-value pair is a common way to store attributes, but the term that specifically means a set of data describing information about other data is metadata. Blob storage is simply the storage place for objects, not the descriptive descriptors themselves.
