A Virtual Machine pertains to an emulated computer system, or distributed systems designed to copy or replicate all the features of the original computer’s architecture. The Virtual Machine includes a virtual CPU, memory, and storage. From the outside, the Virtual Machine appears to bear no difference than a physical machine containing the same hardware.
The Virtual Machine can effectively host websites, run programs, and exist on a network with other systems. Should the user view the Virtual Machine through a screen, it would appear as a window that runs within the computer’s own Operating System. Because of its virtual nature, multiple Virtual Machines can exist together on one server.
