That's the "base" operating system. Let's say you have Windows 7, and you need Windows XP for compatibility (for instance, lots of older games no longer work with Windows 7). So you install a virtual machine using a special program such as as VMWare, and you run Windows XP in a window within Windows 7. (It can be full-screen as well.) Or perhaps you want to try out Linux. In this example, the base machine - the real, physical machine - has Windows 7; that's the host operating system, while the virtual machine has Windows XP (or Linux).Note: It is also possible, for example, for the host operating system to be Windows 7, and the virtual machine also Windows 7 - this can help you isolate different installations, and - for example - if you no longer need it, erase the entire virtual machine, which is faster, and often much cleaner, than uninstalling.
