Solution
The correct answer is: A large program is broken down into smaller parts, which are stored on a secondary device.
When a computer uses virtual memory, it is essentially using a portion of the hard drive as if it were additional RAM. This happens when the actual RAM is full. The operating system moves data that is not currently in use to a space on the hard drive, freeing up RAM for other applications. This process is known as paging or swapping.
The data stored in virtual memory will be swapped back into RAM when it is needed again. This allows a computer to run larger programs or multiple programs at once, even if it doesn't have enough physical RAM to handle all the data.
So, the process of using virtual memory involves breaking down a large program into smaller parts, which are then stored on a secondary device (the hard drive) until they are needed again.

Describe how virtual memory works
Five programs are currently being run in a computer. Program 1 is using 10 GiB of RAM,program 2 is using 5 GiB of RAM, program 3 is using 12 GiB of RAM and program 4 isusing 4 GiB of RAM. The programs are at the stage where program 5 now needs to accessRAM, but RAM is presently full (RAM has a 32 GiB maximum capacity). Explain how virtualmemory could be used to allow program 5 to access RAM without any of the data from theother four programs being lost. Explain why it would be beneficial to get more RAM insteadof relying on virtual memory
