What is Virtual Memory?
Virtual memory combines your computer’s RAM with temporary space on your hard disk. When RAM runs low, virtual memory moves data from RAM to a space called a paging file. Moving data to and from the paging file frees up RAM to complete its work. The more RAM your computer has, the faster your programs will generally run. If a lack of RAM is slowing your computer, you might be tempted to increase virtual memory to compensate. However, your computer can read data from RAM much more quickly than from a hard disk, so adding RAM is a better solution.
How Does Virtual Memory use a Page File on the Hard drive to extend the memory?
What are the Benefits and Drawbacks or Virtual memory?

However, Applications run slower.It takes more time to switch between applications.Less hard drive space for your use.
