consider the organization of a Unix file as represented by inode. Assume that there are 12 block pointers and a singly,doubly and triply indirect pointers in each inode. Further assume that block size of system and disk sector size are 8KB. The disk pointer is 32bits and maximum file size is 16MB.
Assuming no information other than file inode is in main memory. How many disk accesses are required to access a byte in position 13423826 of the file?
