Which response type indicates readiness for data transfer?

The response type that indicates readiness for data transfer is the Transfer Ready Response. This response serves as an explicit signal from the system that it is prepared to commence the data transfer process. It ensures that both the sender and receiver are synchronized and ready to exchange data, which is critical for maintaining data integrity and throughput efficiency during the transfer.

When a system generates a Transfer Ready Response, it conveys that all necessary preparations have been completed, such as buffer allocation and establishing any required connections. This helps to prevent issues such as data loss or corruption that could arise if data were sent without proper readiness. The other response types, while relevant, do not specifically indicate that the system is prepared to transfer data at that moment.
