                were in Real Mode, while providing the protection and
                address-mapping capabilities of Protected Mode to a
                supervisor program which oversees the virtual machine on
                which the user programs are running. This mode is called
                Virtual-86 because one or more virtual 8086 environments are
                run on a single CPU.
