Answer 2

The computer can move ‘data and instructions’ between ‘storage and memory’ as needed, in a process called swapping.

Answer: Option B

Explanation:

In order to replace or exchange a segment or a piece of data in memory, swapping should be done. It is a sort of useful technique which enables the computer in executing the programs and manipulates the data files that are larger than ‘main memory’.  

The OS is supposed to copy as much data to be copied as possible into main memory, and the remaining non-copied data are left on the disk. Whenever the OS needs the data resided in the disk, it will exchange the part of data into the main memory with the data in the disk.
