	I don't know which computer dictionary you are using.  To me,
	virtual memory is a logical memory.  The address space of
	virtaul memory is, usually, >> that of physical one.  The
	mapping is just a mechanism to convert the logical memory
	space to the physical one (in run time).  I believe you
	need a better dictiionary.
