The previous problem is in the picture. Suppose that I have 800 Gigabytes worth of movies on my hard drive at home, and I’d like to get them to a friend in Chicago. I could either send them over the Internet, or I could copy them to a thumb drive, drive to Chicago, and deliver them by hand. Assume that the specs for my cable connection are the same as in the previous problem, but the friend in Chicago has a cable connection which gets 25 Mbps down/5 Mbps up. Which would be faster? Show your work.

Suppose that I have a 6.5 GByte movie file that's sitting on my hard drive at home. If I have cable internet service, which gets 50 Mbps down and 10 Mbps up, how long before my friend is able to get the file if he has a DSL which gets 8 Mbps down/1 Mbps up?

Expert Solution
Step 1: Trivia

25 Mbps down implies downloading speed and up implies uploading speed.

Converting from Bytes to bits:

1 GBits = 230 bits.

1 Byte = 8 bits.

1Mbps = 106bps
