What is Demand paging?

Virtual memory is commonly executed by demand paging. In demand paging, the pager brings only those essential pages into memory instead of swapping in a whole process. Therefore it avoids reading into memory pages that will not be used anyway, reducing the swap time and the amount of physical memory required.
