3. The entire movie Jurassic Park is stored on a video server and occupies 1.35GB. You want to download it onto your computer in 30 minutes. What should be the link speed to accomplish this? If you were to get the same movie through a telephone line operating at 56 Kbps, how long will it take to transfer the movie from the video server to your computer? How long will it take when you use a cable modem of 1.5 Mbps?
