A question for DONI...

DONI I have often heard you & HAIYAKU refer to DOS to MOS
I was wondering if you could help me to better understand the full benefits of this. First of all let me try to state in laymens terms of how I think I understand it & if I am wrong in any way please do correct me. There are basically 4 types of DATA Structure

1. contiguous
2. linked list
3. linked list indexed
4. indexed inode tables

The first two types used mostly in prortable handhelds the 3rd used by MSFT & the 4th used by LINUX.
Now I am mostly curious about the 3rd one used by MSFT. If I understand correctly the 3rd one is the same as the 2nd one except that it has a file allocation table (FAT)with it. The problem with FAT other than it being an overhead burden is that it supports set sizes & as the memory increases so does the size of the clusters. The problem with this is that if you have a cluster that is say 4k than you are throwing away alot of space.

I guess what I am trying to say is if a cluster is a bucket that holds 4 litres of water but the file that you store in it is only 1 litre than the 3 ltres of space that is left over just becomes a waste of space. With MOS the entire 4 litres is used up or close to it. Does this sound correct if so I was wondering what is the diference I as a pc user would notice if I were to be using MOS operated PC as opposed to a DOS.
