Hi all,

Could anybody answer these questions for me? My little brother is applying for a job and has been told by the recruiter that they may ask questions such as these in the interview, I dont have much exp with Linux and want to make sure he gives a good answer!

What do level 2/3 file systems mean/do on a LINUX system?
What advantage(s) if any does a UNIX system have over LINUX one?

Thanks for you help guys/gals!
