On a computer, what is "virtual memory" and is it the same as "% free space"?
by

1 Answer

Answer :

Virtual memory is stored on your hard drive. It works as additional memory space, allowing your computer to run better. You need to make sure that you always have enough free space on your HD. If you are low on space then your computer will run slowly. To see how much virtual memory is being used, right click on My Computer and go to Properties. Click on the advanced tab. Select Settings under Performance and then click on the advanced tab. Look under virtual memory to see how much space is allocated to VM. Make sure you always have that much space free on your hard drive.
