How to manage virtual memory in an OS; Bottom line; How virtual memory works. Virtual memory is an area of a computer system’s secondary memory storage space, such as an HDD or SSD, that acts as if it were a part of the system’s RAM or primary memory. Ideally, the data needed to run applications is stored in RAM, where the CPU …It is installed over a pre-existing operating system and that operating system is called the host operating system. In this virtualization, a user installs the virtualization software in the operating system of his system like any other program and utilizes this application to operate and generate various virtual machines.The technique is exploited by a computer’s operating system (OS) in situations when the system lacks sufficient RAM to execute instructions. With virtual memory, computers can run complex and sophisticated programs as the conflicting memory demands of multiple programs are met within a fixed memory space.
