Virtual server
A virtual machine behaves like a server. It is a computer within a computer that gives the user the same experience they would have on the host operating system itself. In general, virtual machines are isolated from the rest of the system, meaning that the software in the virtual machine cannot escape or tamper with the underlying server itself.
