What is virtual memory?
An area of the hard dfisk/ solid state drive used only when RAM has become too full and can not fit any more programs in it. It is temporary (only when RAM is too full) and when used results in a significant decrease in performance for the computer.

When data is swapped between RAM and Virtual memory, which programs are transferred?
The least recently used programs are the first to be swapped into virtual memory and if it is needed again, it will be swapped back in at the expense of other programs.

Your computer is running really slowly? What is one way you can improve the performance?
Add more RAM so more programs can run at once without Virtual memory being affected.
