Two peer processes A$($sender$)$ and B $($receiver$)$use stop and wait ARQ tosend packets over a single link with capacity C$.$ All packets have the samelength of $100$ bits. The round trip time $($which is the time until A receives anacknowledgement for a sent packet$)$ is equal to $2$ seconds. Assume that nopackets or ACKs are dropped and that all packets and ACKs arrive error free.Furthermore, assume that the capacity C is equal to $100,000$ bps$.$a$.$ Find the average transmission rate with which process A sends datato process Bb$.$ What is the link utilization?
