Quote from the first search result Google:Virtual memory is simulated RAM. When you have use up all your RAM, your computer will shift data to an empty space on the hard drive. Computer swaps data to the hard disk and back to your RAM as needed. When you increase your virtual memory you are increasing the empty space that is reserved for your RAM overflow.
