C) Figure below illustrates the disk space containing the file boo stored in some blocks sequentially. 0 1 N 3 4 5 6 7 8 9 10 11 12 13 14 15 Directory: file start boo 2 end 23 16 17 18 19 -1 Used block 20 21 22 23 Free block i) Assuming that each block can only store 4 block address, show how the free space is represented using Grouping technique by determining the values of a) - o) as illustrated in the diagram below d) e) f) h) i) j) k) 23) Block a) Block b) Block c) The value of Block a) is = The value of Block b) is = The value of Block c) is = The value of d) is = The value of e) is = The value of f) is = The value of g) is = . The value of h) is = . The value of i) is = The value of j) is = The value of k) is = The value of I) is = The value of m) is > The value of n) is = The value of o) is = ii) Explain the difference between grouping and counting Grouping is a counting . while
