Compute the number of packets that you would need to transfer a file of $50$MB on each of the following networks. Assume that the Transport layer adds an $8-$ byte header and the Network layer adds a $20-$byte header to each packet. Enter an integer number without any commas or spaces. $1.$ A Fast Ethernet with a $1500$ byte MTU $($maximum transmission unit$).2.$ A Gigabit Ethernet $($GbE$)$ with a $9000$ byte MTU.Compute the number of bytes you would need at the Link Layer to transfer a file of $50$MB on each of the following networks. Assume that the Transport layer adds an $8-$byte header, the Network layer adds a $20-$byte header and the Link layer adds a frame header of $14$ bytes and trailer of $4$ bytes to each packet. Enter an integer number without any commas or spaces. $1.$ A Fast Ethernet with a $1500$ byte MTU. $2.$ A Gigabit Ethernet with a $9000$ byte MTU. $($Note: The Ethernet frame header and trailer bytes are not part of the MTU size$).$
