demand-paging-the transfer of page from secondary memory to
primary memory at the moment of need.
pre-paging-the retrieval of a page other then demanded by a
page fault.the hope is that the additional page will be
needed in near future.

Answer / guest
With demand paging, a page is brought into memory only when
a location on that page is actually referenced during
execution. With pre-paging, pages other than the one
demanded by a page fault are brought in.
The selection of such pages is done based on common access
patterns, especially for secondary memory devices.

Answer / terry xaviour
demand paging is a process that accesses its working set by
page faults every time it is restarted.
pre-paging is a technique whereby the operating system in a
paging virtual memory multitasking environment loads all
pages of a processors working set into memory before the
process is restarted.
