$).$ Compare Go$-$Back$-$N and Selective Repeat. Assume that

the timeout values for the two protocols are sufficiently long such that five

consecutive data segments and their corresponding ACKs can be received $($if not lost

in the channel$)$ by the receiving host $($Host B$)$ and the sending host $($Host A$)$

respectively. Suppose Host A sends five data segments to Host B$,$ and the second

segment $($sent from A$)$ is lost. In the end, all five data segments have been correctly

received by Host B$.$

$1.$ How many segments has Host A sent in total? What are their sequence

numbers? $($e$.$g$.$ the total is $3$ and sequence numbers for segments are: $1,2,$ and

$4).$

$2.$ How many ACKs has Host B sent in total? What are their sequence numbers?

$($e$.$g$.$ the total is $3$ and sequence numbers for segments are: $1,2,$ and $4).$

Answer this two questions question for the two protocols $($Go$-$Back$-$N and Selective
