What is paging(OS-8)

Paging


-Paging is storage mechanism that allows operating system to retrieve a process from the secondary memory into the main memory in the form of pages.
-In the paging method the memory is divided  into small fixed size block of the physical memory that is called frame.
-The size of the frame should be kept the same as that of pages to have maximum utilization of the main memory and to avoid external fragmentation.
-Paging is use for the faster access to the data and it is a logical concept.

What is demand paging(OS-9)

Demand paging -Loading the entire program in the physical memory at program execution time is not so good because the user does not need the entire program in memory at a time. -An alternative strategy is to load pages only as they are need this technique is known as demand paging. -With demand paging virtual memory, pages are only loaded when they are demanded during program execution pages that are never accessed thus never loaded into physical memory.    -A demand paging system is a similar to paging system with swapping, -But here it uses a lazy swap where it never swap a pages into memory unless that page will be need. -In demand paging pager is more suitable than swap er.
