A PC emulator, or virtual machine, is software that mimics the functionality of a physical computer. It allows you to run an operating system (OS) on top of another OS, without affecting the host machine. This means you can test and run different OSes, like Windows 7, on your current computer without dual-booting or affecting your primary OS.
