NASA has a new $600-$Mbps point$-$to$-$point link set up between the earth and a robot

on the Mars planet. Given that the planet Mars and earth are at their closest instance,

i$.$e$.54\mathrm{.}6$ million kilometers apart, and that data travels over the link at the speed of

light $3\backslash$times $108$ m$/$s$.$

i$.$ Calculate the minimum Round$-$Trip Time $($RTT$)$ for this link. $(2)$

ii$.$ Using the RTT as the delay, calculate the delay $\backslash$times bandwidth product for the

link. $(2)$

iii. What is the significance of the delay $\backslash$times bandwidth product as computed in $($ii$.)$

above? $(3)$

iv$.$ The robot$$s sensors$,$ cameras and other data capturing equipment save their

data on disks. Suppose NASA wishes to download the most current image,

which is $80$ MB$.$ Compute the transmission time for this file? $(3)$

v$.$ How much time will it take NASA on earth to send an image request to the

robot on Mars to when the image is received?
