A virtual computer system is known as a “virtual machine” (VM): a tightly isolated software container with an operating system and application inside. Each self-contained VM is completely independent. Putting multiple VMs on a single computer enables several operating systems and applications to run on just one physical server, or “host.” 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.
