i) An operating system contains three resource classes, namely R1, R2 and R3.The number of resource units in these classes is 7, 7 and 10 respectively.The current resource allocation state is as shown below :Process Allocated Resources Maximum RequirementR1 R2 R3 R1 R2 R3P1 2 2 3 3 6 8P2 2 0 3 4 3 3P3 1 2 4 3 4 4A) Is the current allocation state safe ? (5)B) Would the following requests be granted in the current state ?• Process P1 requests (1, 1, 0)• Process P3 requests (0, 1, 0)• Process P2 requests (0, 1, 0) (2+2+2=6)ii) Consider a typical disk with a advertised average seek time of 20 ms, atransfer rate of 1 MB/s and 512-byte sectors with 32 sectors per track.Suppose we wish to read a file consisting of 256 sectors for a total of128 KB, estimate the total time of the transfer.
