Hi all,

Recently I was going thru the Windows Fundamentals material. It was given that Windows NT OS is a 32-bit OS and so the Virtual memory will be 2^32 (2 raised to the power of 32)bytes = 4GB of which upper 2GB belongs to Kernel and the lower belongs to user. I am really stuck up at this point due to confusion. Does this mean that a 32-bit OS needs a minimun of 4GB Hard disk? Actually what concepts do make up an n-bit OS? I have got a flair to learn low level programming and i have taken a amatuer step n got locked. Can anybody please help me understand the concept of how the virtual memory is really implemented in Windows? :?:
