Converting numbers from base 2 to base 10:
1. 1011 = 11
2. 101010 = 42
3. 11111 = 31
4. 10010 = 18

Converting numbers from base 10 to base 2:
1. 31 = 11111
2. 51 = 110011
3. 7 = 111
4. 103 = 1100111

How long will it take to download a 100MB file on each of the following connections:
1. a modem at 56KB/second
1KB/s = .125 KB/s = 56 KB/s = 7 KB/s = 100,000 KB/7KB/s = 3.97 H
2. DSL at 5 megabits/second
1MB/s = .125 MB/s = 5 MB/s = .625 MB/s = 100 MB/.625MB/s = 2.66 Min
3. high-speed connection at 10 Megabits/second
1MB/s = .125 MB/s = 10 MB/s = 1.25 MB/s = 100 MB/1.25MB/s = 80 Sec

If an internet connection an upload 3 megabits/second, and an MP3 is 60 Megabytes, how many MP3s can you upload in an hour?
3 MB/s = .325 MB/s = x/.375 MB/s * 3600 Seconds = 1350 MB / 60 MB = 22.5 Mp3s
