Suppose we are using a RAID level 4 scheme with four data
disks and one redundant disk. As in Example 13.9 assume blocks
are a single
byte. Give the block of the redundant disk if the corresponding
blocks of the
data disks are:
a) 01010110,11000000, 00111011, and 11111011.
b) 11110000, 11111000, 00111111, and 00000001.
