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. It’s used by operating systems to simulate physical RAM by using hard disk space. To understand how virtual memory works we have to go back in time, before virtual memory even exited. In the days of Windows version 1 or 2, we actually couldn’t run many applications if we didn’t have enough physical RAM installed. As we know, the system itself is using a portion of RAM. If we run more applications, each application will also get its own portion of RAM. If we run too many applications, at one point we will run out of RAM. At that point we won’t be able to open any additional application. Back in those days we had to live with that. If we don’t have enough memory, we can’t run applications.
This tutorial will apply for computers, laptops, desktops,and tablets running the Windows 10 operating system (Home, Professional, Enterprise, Education) from all supported hardware manufactures, like Dell, HP, Acer, Asus, Toshiba,Lenovo, and Samsung).
