Q. Explain the process of piggybacking?
When a data frame arrives in its place of immediately sending a separate control frame and the receiver restrains itself and waits until the network layer passes it the next packet. The acknowledgement is connecting to the outgoing data frame (using the ACK field in the frame header). In consequence the acknowledgement gets a free ride on the next outgoing data frame. The technique of momentarily delaying outgoing acknowledgements so that they can be hooked onto the next outgoing data frame is known as piggybacking.
