A virtual machine is a a software that allows users to install multiple operating systems within an operating system. For example, if you are running Mac OS, you can install Ubuntu and Microsoft Windows inside the virtual machine.

VirtualBox is an opensource virtual machine software. I found that it is easier to install and use than Parallels and VMware Workstation.
