What does the term "bulk data" refer to in the context of financial transactions?

The term "bulk data" in the context of financial transactions generally refers to large volumes of data transmitted or processed simultaneously. This can involve extensive datasets that include transaction records, customer information, or other pertinent information that needs to be processed in bulk for efficiency.

While the technical specifications for mainframe communications, such as file formats or protocols, can be part of handling bulk data, the core concept is about the volume and type of information rather than the specific technical details. The other options—file transmission rates, methods for posting online messages, and transaction processing fees—focus on different aspects of financial operations rather than the definition and understanding of bulk data itself.

Overall, the term "bulk data" is most appropriately linked to how large sets of transactional or customer data are handled, aligning closely with the need for efficient data management in financial systems.
