Filesystems and Storage Checkpoint

1. Direct blocks are:

Stored directly in the inode Stored in a separate index file Always on disk end Only for metadata

2. Single indirect blocks contain:

A list of data block pointers File contents Process IDs TLB entries

3. LOOK differs from SCAN because:

It only goes as far as the last request It always reverses at disk end It ignores direction It is random

4. True/False: Disk scheduling seeks to reduce total head movement.
