(Solved) : 3 File Systems Consider File Size 10 000 000 Bytes System Block Size 2000 Bytes Using Base Q37275353 . . .

3. File Systems: Consider a file of size 10,000,000 bytes on asystem with block size of 2000 bytes (I am using base 10 to makethe computations easy). The file system uses 32-bit pointers.Assuming that the file control block, i-node, directory entry, andFAT (as appropriate) are already in memory. How many disk accessesare required to read byte number 9,000,050 if the system uses eachof the following types of allocation (a-d)? How many memory readsare needed to find the correct block (only count reads toallocation structures, not instructions or local variables),starting with the read of the directory entry? Show your work.

a. Contiguous storage.

b. Sequential storage.

c. FAT.

d. Unix file system, with 12 direct pointers per i-node.
