a.
Computer has 1GB NIC with it but it has optimized to push up to 80%.
So NIC capacity = 800Msps
= 800 * 10^6 bytes per second
p/s = NIC capacity/size of each packets
= (800 * 10^6) / 1500 = 533333.33 packets/ second
b. for 64 byte packets we need to divide it by 64.
p/s = NIC capacity/size of each packets
= (800 * 10^6) / 64 = 12500000 packets/ second
d. Time = file size/ available bandwidth
T = 20 GB/100Mbps Note : 1GB=1024MB
= 20 *1024 Mb/100Mbps
= 204.8 second
(60)*3 + 24.8 sec = 3 min and 24.8 second
So the answer is 3 minutes and 24.8 second
