Type the following:


                              1 byte = 8 bits            1 GB = 1024 MB            1 EB = 1024 PB
                              1KB = 1024 bytes           1 TB = 1024 GB            1 ZB = 1024 EB

                              1 MB = 1024 KB              1 PB = 1024 TB           1 YB = 1024 ZB


                          Make a list of storage devices.
