Show answer & explanation
Correct answer: B
Concept
In bidirectional data communication, control information can sometimes share a frame with payload data instead of being sent in a separate frame.
When a receiver briefly delays its acknowledgement and places it in the next reverse-direction data frame, the technique reduces separate acknowledgement traffic.
Application
The stem describes a delayed outgoing acknowledgement being attached to the next outgoing data frame. This is exactly the mechanism called piggybacking.
Contrast
Bit stuffing inserts extra bits to keep a data pattern from being confused with a framing flag.
Pipelining allows several frames or requests to be outstanding before earlier ones are acknowledged.
Broadcasting sends a transmission toward multiple recipients rather than combining an acknowledgement with data.
Cross-check
The defining action in the stem is attaching an acknowledgement to a reverse-direction data frame, so Piggybacking is the matching term.
Result
Therefore, the required technique is Piggybacking.
