Answer 2

ANSWER:

Demand paging brings a page into memory only if it's needed.

EXPLANATION:

Demand paging allows the execution of programs larger than the size of physical memory. It brings a page into memory only if it's needed.

It is the same as a paging system with swapping. Using this, a page is loaded into main memory only it is referenced a location on that page.

Following are few key points about demand paging:

• The features of simple paging and overlaying is combined to implement virtual memory.
• Any page of the program is stored contiguously within the paging swap space on secondary storage device.
• When the page is in the memory, it is accessed as in simple paging.
• Some kind of Hardware support is required to differentiate between those pages that are in memory and those are on the disk. Valid and invalid bits are used for this.

Demand paging brings a page into memory only if it's needed.
