Which term describes a collection of binary data stored as a single entity?

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

Answer: (A)

A binary large object is a single, opaque sequence of bytes that represents a file or data blob. In storage systems, this data is kept as one unit called a blob, so blob storage is the service designed to hold these objects as individual entities. This description fits best for a collection of binary data stored as a single entity, such as an image, video, or PDF, without imposing a fixed schema on the contents.

A key-value pair, by contrast, is just a simple association between a key and a value, not a single binary object. Metadata refers to information about data (like size, type, or timestamps) rather than the binary content itself. A tag is a label used for organization or search, not the storage unit for binary data.
