Define source -initiated transfer using handshaking

Source-initiated transfer using handshaking is a method used in data communication to ensure that data is transferred accurately and efficiently from a source device to a destination device. Here's a step-by-step explanation:

1. Initiation: The source device initiates the data transfer process. This is typically done by sending a signal or a specific data packet to the destination device.

2. Handshaking: The destination device responds to the source device's signal with an acknowledgement signal. This process is known as handshaking. It establishes a connection between the source and destination devices and ensures that the destination device is ready to receive data.

3. Data Transfer: Once the handshaking process is complete, the source device begins to transfer data to the destination device.

4. Acknowledgement: After receiving the data, the destination device sends an acknowledgement signal back to the source device. This confirms that the data has been received correctly.

5. Termination: Once all the data has been transferred and acknowledged, the source device terminates the connection.

This method is particularly useful in networks where data integrity is crucial, as it allows for error checking and correction. It also helps to prevent data loss by ensuring that the destination device is ready to receive data before the transfer begins.
