You are confusing memory (physical address space) with virtual address space. You can put more than 4GB of memory into a 32-bit system; you don't need to move to 64-bit to gain physical address space. Each process gets its own virtual address space, so each one will get its own 2GB of user-mode address space to play with.
(Or 3GB if /3GB or 4GB if running on WOW64 with /LARGEADDRESSAWARE.).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
