Hi,
can anyone tell,what mean by paging?


Thanks,

paging refers to the process of managing program access to virtual memory pages that do not currently reside in RAM. It is implemented as a task that resides in the kernel of the operating system and gains control when a page fault takes place. Its main functions performed are:

• determine the location of the data in auxiliary storage.
• determine the page frame in RAM to use as a container for the data.
• write the existing page to auxiliary storage if it has been modified since it was last loaded.
• load the requested data into the available page.

The fault that triggers this operation is caused by a program trying to reference an address within a page that is not currently residing in RAM.
