With VirtualBox, you can run unmodified operating systems – including all of the software that is installed on them – directly on top of your existing operating system, in a special environment that is called a “virtual machine”. Your physical computer is then usually called the “host”, while the virtual machine is often called a “guest”.
The following image shows you how VirtualBox, on a Ubuntu host, is running Linux Mint as guest operating system in a virtual machine window:
