Question $1$

A MAC sub$-$layer of a sender host in a $10-M\frac{b}{s}$ Classic Ethernet receives payload

from the upper layer to send it to the destination.

$($i$)$ Consider the case when the payload of $1200$ bytes to be placed in the data field of

the Ethernet frame which is shown in Figure $1\mathrm{.}1.$ How long does it take for a host to

transmit this Ethernet frame?

Figure $1\mathrm{.}1$

$($ii$)$ Consider now the case when transmission of the frame with the payload of $40$

bytes suffers $7$ successive collisions. Find the collision probability after $7$ collisions.

Calculate the shortest and the longest waiting time $($in seconds$)$ for the transmitting

stations.
