● The usual way to ensure reliable delivery is to provide the （71） with some feedback about what is happening at the other end of the line. Typically, the protocol calls for the receiver to send back special （72） frame. bearing positive or negative （73） about the incoming frames. If the sender receives a positive acknowledgement about a frame, it knows the frame. has arrived safely. On the other hand, a negative acknowledgement means that something has gone wrong, and the frame. must be transmitted again. An additional complication comes from the possibility that hardware troubles may cause aframe. to （74） completely. In this case, the receiver will not react at all, since it has no any reason to react. It should be clear that a protocol in which the sender transmits a frame. and then waits for an acknowledgement, positive or negative, will hang forever if a frame. is ever lost due to, for example, （75） hardware.（71）A. receiverB. controllerC. senderD. customer（72）A. dataB. controlC. requestD. session（73）A. applicationB. connectionC. streamD. acknowledgement（74）A. vanishB. varyC. appearD. incline（75）A. actingB. workingC. malfunctioningD. functioning
