Answer: 3: paging

Paging is the take and put method of transferring data between the main memory and secondary memory say hard disk for example in the form of page. When a program needs more space than is actually available in the physical main memory, the operating system swaps out, that is transfers inactive portions of memory to the secondary memory. This movement from one page to another of main memory and disc or storage is known as paging. This is a memory management technique commonly employed by modern operating systems to enable running of programs whose total memory demand is actually more than the total physical memory that is available; one which only loads into actual main memory only the pages that are needed at a particular time, at least in part.
