What is Virtual Memory. Virtual memory is a component of most operating systems, such as MAC OS, Windows and Linux. Virtual memory has a very important role in the operating system. It allows us to run more applications on the system than we have enough physical memory to support. Virtual memory is simulated memory that is written to a file on the hard drive. That file is often called page file or swap file.
I'm getting a Virtual Memory is Low error message. First off, understand that virtual memory is a part of the computer's hard drive that is set aside and used like RAM by the operating system. When the physical RAM is all used up, the operating system begins to use the virtual memory.hen the virtual memory is nearly all used up, the Virtual Memory is Low warning message will pop up. If you have multiple programs open at the same time and they are using up the majority of your RAM and virtual memory, this can cause the warning message to pop up.
