(Please provide a detailed solution about the conversion between them. Thank you! I am stuck at this!! And what does the "5% overhead" mean?)

1. Find how many years does it need to transfer the 100 PB data through 100 MHz broadband network.

2. Calculate the data transferring time through Google Fiber(1 G bits/sec).

3. How long will it be if the cable connection is provided by xfinity(2,000 M bits/sec)?

= Note: 1 Byte 8 bits For the network transmission, assume 5% overhead (times 1.05 with the size of data you want to send). - = 103 = 1 Kbits 1 Mbits 1 Gbits bits= 1000 103 Kbits= 1000 103 Mbits= 1000 bits Kbits Mbits = - 1 KB 1 MB 1 GB 1 TB 1 PB 1 EB 210 B = 1024 210 KB 1024 210 MB 1024 210 GB 1024 210 = 1024 210 PB = 1024 B KB MB GB PB = =
