MongoDB stores data in which format?

MongoDB stores data in which format?

• A. JSON in plain text.
• B. BSON (binary-encoded JSON-like documents).
• C. XML.
• D. CSV.

Answer: (B)

MongoDB stores data as documents in a binary-encoded JSON-like format called BSON. This means you interact with JSON-like structures through drivers and the shell, but the on-disk storage is BSON, a binary representation that is faster to parse and supports more data types (such as dates, binary data, and various numeric types) than plain JSON. BSON also preserves the hierarchical document/array structure, which is essential for MongoDB’s document model. In contrast, plain text JSON, XML, or CSV aren’t used as the storage format in MongoDB.
