Answer / Neha Kumari

MongoDB architecture consists of multiple components:
1. Databases: A container that holds collections.
2. Collections: An ordered set of documents that share a schema.
3. Documents: JSON-like objects with dynamic schemas that can store arrays, objects, and other complex data types.
4. Shards: Logical splitting of a database to distribute data across multiple machines for increased performance.
5. Replicas: Copies of a shard or collection used for redundancy, high availability, and read scaling.
