Answer is Wrong!
Answer is Right!
The correct answer is C. selective recovery.
In reliable data transfer, the last step is to recover any lost or corrupted messages. This is done by using a technique called selective recovery, which involves identifying the messages that have been lost or corrupted and then retransmitting them.
The other options are incorrect because they are not the last step in reliable data transfer.
- A. initialization is the first step in reliable data transfer. It involves setting up the connection between the sender and receiver.
- B. message relaying is the second step in reliable data transfer. It involves sending the messages from the sender to the receiver.
- D. lost message detection is the third step in reliable data transfer. It involves detecting any messages that have been lost or corrupted.
