When Windows opens a program, it distributes a certain amount of random access memory (RAM) to the program in order to keep it running smoothly. RAM is hardware installed into the computer and cannot be changed--if you only have 512 megabytes (MB) of RAM installed, that is all you can use. Virtual memory is used when RAM runs out, and can be anywhere from one and a half to four times the size of your RAM--but it does run slower. For this reason, it is important to know how much virtual memory your computer has.
