Questions 1) Is it possible to have a disk contain over 50% fragmentation when using a contiguous allocation file system? How about a linked file system? Justify your answer.

2) You overhear one of your classmates saying that any space considered internal fragmentation must not be on the free list while any external fragmentation must be on the free list. Is this statement correct? Justify your answer.

3) Consider a file system that uses inodes (indexed allocation) to represent files. Disk blocks are 4-KB in size and a pointer to a disk block requires 4 bytes. This file system has 12 direct disk blocks, plus single, double, and triple indirect disk blocks. What is the maximum size of a file that can be stored in this file system? Show your work.
