Virtual computing enables computers to run multiple operating systems as programs installed on a host operating system with virtual networking. Networks that are virtual can establish connections to a physical network and to the Internet. VirtualBox is a program that can support virtual computing and virtual networking with several operating systems, including Windows 7. VirtualBox networking does not work with Windows 7 until you install additional components and update the driver configuration.
