4. You are trying to transfer the contents of a 1.25terabyte disk drive between here and New York, and have at your disposal two methods: (a) sending the data over a 100mbps link or (b) sending the drive by Federal Express (with a guarantee that it will arrive in 24 hours). Assume the network charges 10 -10 cents per bit transmitted, and Federal Express charges $30 for the package. Which option is faster? Which option is cheaper? Time to transmit the data over the link ¿ 1.25 terabytes 100 mbps ¿ 1.25 8 10 6 100 1 terabit = 10 6 megabit ¿ 100000 seconds = 1.15 days Time to transmit data using FedEx = 1 day, meaning that the FedEx option will be faster. Cost to transmit the data over the link ¿ 1.25 8 10 12 10 10 = 1000 cents = $ 10 Cost to transmit the data using FedEx ¿ $ 30 Since $30 is greater then $10, the network option will be cheaper.
