Use the information from problem 37 and the fact that a 56K modem will download at a rate of 56 kilobits per section under ideal conditions to answer the following questions. (Note: A kilobit is 1024 bits.)

a. Suppose music is downloaded under ideal conditions via a 56K modem. How long will it take a 4-minute song to download?

b. MP3 is a compression system for music. It reduces the number of bytes in a song without reducing the quality significantly. If the number of bytes is reduced by a factor of 10, then how long will it take a 56K modem to download a 4-minute song in MP3 format?

c. You may be able to connect to the Internet using a Digital Subscriber Line (DSL). DSL is a high-speed connection that uses the existing telephone line. Assume that DSL can download at a maximum rate of 512 kilobits per second. How long would it take a DSL to download a 4-minute song?

Problem 37: Manufacturers store music on a CD digitally as 0s and 1s. Music is sampled 44,100 times per second. Each sample is 2 bytes (16 bits). Separate samples are taken for the left and right speakers. For a 4-minute song, how many bits are sampled?
