Operating Systems 2014F Final Exam Review

Concepts

• file sizes (logical versus blocks consumed)
• mounting a fs
  • changes in filesystem hierarchy
  • concept of a "root" filesystem
  • privileges required
• loopback mounts and files
• holes in files
• stat on files

Sample Questions

• If a program "seek"'s on a zero length file to position 100,000 and then writes one byte, what would you expect the file's logical length to be? What about its physical size (space consumed on disk)?
