reducing misses in cache..

Question

which of the following statement (if any) are generally true?

1. There is no way to reduce compulsory misses.

2. Full associative cache have no conflict misses.

3. In reducing misses, associativity is more important than capacity.

Answer 1

1) No,  compulsory miss can be reduced. It is like all places in cache is empty and No block yet  came. So to reduce compulsory miss take some block in cache

2)No, Conflict miss is there , when there is no place empty in cache. Associativity cannot say there is no conflict misses

3) No, I think  they are equally important  

   Associativity is for conflict misses

 when Capacity is for capacity misses

i think 2nd is true, how it will have conflict miss, no particular slot is assigned , as long as we have space left we can always assign to that block

why 2^nd one is false i didn't get?
