Rather they are swapped in only when the process needs them (On demand). This is termed as lazy swapper, although a pager is a more accurate term. Initially only those pages are loaded which will be required the process ...

SpletSwapping is a memory management scheme in which any process can be temporarily swapped from main memory to secondary memory so that the main memory can be made available for other processes. It is used to improve main memory utilization. In secondary memory, the place where the swapped-out process is stored is called swap space. SpletPaging is a function of memory management where a computer will store and retrieve data from a device’s secondary storage to the primary storage. Memory management is a crucial aspect of any computing device, and paging specifically is important to the implementation of virtual memory.

The main idea behind the … SpletDemand paging is a technique used in virtual memory systems where the pages are brought in the main memory only when required or demanded by the CPU. Hence, it is also called lazy swapper because the swapping of pages is done only when the CPU requires it. Virtual memory is commonly implemented in demand paging.
