1.	The technique of temporarily delaying outgoing acknowledgements so that they can be hooked onto the next outgoing data frame is called ____________(a) piggybacking(b) cyclic redundancy check(c) fletcher’s checksum(d) parity checkThis question was posed to me during an interview for a job.Enquiry is from Data Link Layer topic in chapter OSI Model of Computer Network
Answer» The CORRECT choice is (a) piggybacking The explanation: Piggybacking is a technique in which the acknowledgment is TEMPORARILY delayed so as to be hooked with the next outgoing DATA FRAME. It SAVES a lot of channel bandwidth as in non-piggybacking system, some bandwidth is reserved for acknowledgement.
