A disk has a capacity of two tera-byte size. Say the file system uses a multi-level inode structure for locating the data blocks of afile.The inode stores pointers to data blocks, including a single indirect block, a double indirect block, and several direct blocks in the 64 B of available space.Now, it is given that the disk has a block size of 512 B. The maximum file size that can be stored in such a file system in MB (round off upto 2 decimal places).
(a) Suppose a disk drive has 3,000 cylinders, numbered 0 to 2,999. The drive is currently serving a request at cylinder 500 and the previous request was at cylinder 600.

Starting from the current head position, what is the difference between the total distance (in cylinders) that the disk are moves to satisfy all the pending requests for FCFS and SSTF.
