It's not the virtual memory you know from windows (the swapfile) or the swap partition when running some unix. This is about the MMU (memory management unit) which makes sure everything is in memory when needed (ok, the OS actually needs to do this, but the MMU helps) (swapping). 

It also makes sure once userland process cannot write into the memory used by another userland process. It does a few other things, but these are the most important. It maps from virtual addresses into physical addresses.
