What is the correct term for a collection of binary data stored as a single entity?

The correct term for a collection of binary data stored as a single entity is "Binary Large Object Storage," commonly referred to as a BLOB. BLOBs are used in database management systems to store large amounts of binary data, such as images, audio, and video files. They allow databases to manage these types of large files effectively by treating them as a single entity rather than individual pieces of data. This enables efficient storage and retrieval methods designed for large data streams.

In the case of the other options, while they relate to data storage, they serve different purposes. A data warehouse focuses on the analysis of data and storage for reporting and is structured for query effectiveness. Cloud storage, on the other hand, refers to data storage that is harnessed from a network of remote servers hosted on the internet, typically for scalable storage solutions but not specifically for large binary objects. Lastly, a file system is a method and data structure that the operating system uses to manage files on a disk or partition, not specifically oriented toward binary data collections.
