3. Given that the block size of a filesystem is 256B and the filesystem size is 8MB.

What is the size of the physical block number?

If 2-level index allocation is applied, what is the maximum file size in the unit of
MB
supported by the filesystem?

If mixed-level index allocation is applied (in the index block 93.75% are direct physical block numbers, 6.25% are 1-level indirect physical block numbers), what is the maximum file size in the unit of
KB
supported by the filesystem?
