Show answer & explanation
Correct answer: C
Correct answer: handshaking.
Why: In handshaking, the sender indicates that data is available and the receiver returns an acknowledgement signal after receiving it.
Contrast with strobe control: strobe control mainly uses a timing signal to indicate when data is valid; it does not necessarily include a return acknowledgement.
Contrast with piggybacking: piggybacking attaches an acknowledgement to an outgoing data frame, but the general agreement described here is handshaking.
