Sorry, you misinterpret me sir.This is not for any assignment and was certainly not due yesterday.I am a student of Computer Science & Engineering in Calcutta ,India and I am really interested in some details of ext2 file system(yes this the file system which I was considering when I wrote those queries,extremely sorry that I forgot to mention it).If you can furnish me with some links or refer some books , I will be glad to look it up and be evergrateful to you.
