Specify and identify inefficiencies in existing protocols, and formulate new and better protocols. Q$.$ No $2$: $(0)$ Assume that two hosts $($host A and host B$)$ are connected with each other via $2000-$meter$-$long coaxial cable having bandwidth $100$Mbps $($megabit per second$).$ Host A transmits $8000$ bits long segment to host B using the stop$-$and$-$wait transport layer protocol. Assuming the network is error free and all the acknowledgements are received intact then what is the efficiency of stop$-$and$-$wait protocol.
