Is electronic communication always faster than nonelectronic means for longer distances? Calculate the time to send 1000 GB using 25 8-mm tapes and an overnight delivery service versus sending 1000 GB by FTP over the Internet. Make the following four assumptions:
¦ The tapes are picked up at 4 P.M. Pacific time and delivered 4200 km away at 10 A.M. Eastern time (7 A.M. Pacific time).
¦ On one route the slowest link is a T3 line, which transfers at 45 Mbits/sec.
¦ On another route the slowest link is a 100-Mbit/sec Ethernet.
¦ You can use 50% of the slowest link between the two sites. Will all the bytes sent by either Internet route arrive before the overnight delivery person arrives?
