What do you call a filesystem that exists only in memory (not on disk)? (e.g. /dev /proc /sys) 5. What do we call the very top of the filesystem? How do we notate it? 6. Where is root's home folder? (bonus: why is it not in the same location as q.1?) 7. What is different about how UNIX organizes program files compared to Windows? 8. What do we call a .dll (dynamic link library) on a Linux system? 9. List the 7 folders where program executables can be stored. (bonus: what each one is specifically used for) 10. What variable holds the list of directories to search for the executable for a command? 11. Where are temporary files stored (temporarily)? 12.
