i) Give one advantage of the Unix Inode structure over a File Allocation Table that identifies only the first block of a file and requires files to be allocated contiguously on the disk. Give one advantage of the File Allocation Table over the Inode. Under what circumstances would you prefer the File Allocation Table?

ii) Assuming Unix Inodes are being used, and that nothing is cached in memory, how many disk accesses are required to read the first byte of the file "/usr/local/bin/xemacs"? State what is read on each disk access.
