1. Approximately how many images of the size 4MB can be stored on the following devices: (a) a 4.7GB DVD-ROM and (b) the Samsung 2TB (terabyte) Solid State Drive (SSD)? (You must show your calculations! Note that 1GB=1024MB,1TB=1024GB. (a) 4.7GB DVD-ROM (b) 2TB SSD 2. An analog wave representing the song titled "Shallow" by Lady Gaga and Bradley Cooper from the movie "A Star is Born" https://www.youtube.com/watch?v =3ZZddmHlbdU is sampled with the frequency of 44,100Hz during its conversion from the analog form to the digital form. Assume that each sample is stored in 2 bytes. Before you work this exercise, you may click on the above link to listen to this song. You must show your calculations! How many MB would it take to store 4 minutes and 18 seconds of the uncompressed sound? If a compression ratio is 20:1, how many MB would that sound occupy after compression. 3. Find the 16-bit (2-byte) 2's complementary binary representation for the decimal number (30)10. (Note that when you convert the 1's complement to the 2's complement a carry maybe generated. You must show your calculations
