a) Assume there are 1 million books in your campus library. Approximate (to the nearest order of magnitude) how many bytes of data there are if all these books were stored online and accessible across a computer network.
b) How long does it take to transfer the entire collection of books if the data rate of the transmission medium is 10 Mbps, the speed of the original Ethernet? How long does it take if we all have a line with a speed of 1 Gbps? (This value represents the time needed to download your entire campus library.)
