The correct answer is: Asynchronous transfer.

Handshaking programmed data transfer refers to a data transfer method where the sender and receiver coordinate using signals before and during the transfer. This coordination ensures that both devices are ready for data exchange, which is characteristic of asynchronous transfer.

In Asynchronous Transfer, data is sent and received based on readiness signals (handshaking). The sender sends a request signal, and the receiver responds when ready. Commonly used in peripheral communication.

Synchronous Transfer relies on a shared clock signal. Both sender and receiver operate at the same pace, eliminating the need for handshaking.

Interrupt-driven transfer involves using interrupts to signal the processor when a device is ready for data transfer.

While efficient, it does not rely on explicit handshaking signals.

Please explain the given answer.

How it can be called as asynchronous transfer. I think I could be option D.

As handshaking is synchronized and interrupt driven transfer?
