Suppose a reliable data transfer protocol $($Stop$-$and$-$Wait$)$ that uses only negative

acknowledgments $($NAK$)-$ i$.$e$.,$ the receiver sends a NAK when it detects a corrupted

packet, otherwise it does nothing. $($i$)$ If the sender sends data infrequently, would a NAKonly

protocol be preferable to a protocol that uses ACKs? Why? $($ii$)$ If the sender transmits

packets frequently and the end$-$to$-$end connection suffers from very few losses, would a

NAK$-$only protocol be preferable to a protocol that uses ACKs? Why?
