A virtual machine is like another computer ( a virtual computer) running inside of your computer. For instance if you have windows xp, and install a program like vmware server, you can then create virtual computer (machines) that will run linux, windows 98, windows 95, etc. All of these virtual computers can be running at the same time on your windows xp computer.
The original meaning of virtual machine, sometimes called a hardware virtual machine, is that of a number of discrete identical execution environments on a single computer, each of which runs an operating system. This can allow applications written for one OS to be executed on a machine which runs a different OS, or provide execution “sandboxes” which provide a greater level of isolation between processes than is achieved when running multiple processes on the same instance of an OS. One use is to provide multiple users the illusion of having an entire computer, one that is their “private” machine, isolated from other users, all on a single physical machine. Another advantage is that booting and restarting a virtual machine can be much faster than with a physical machine, since it may be possible to skip tasks such as hardware initialization
Virtual Machine basically means running multiple OS’s on the same box. For ex. Virutal PC or Boot Camp allows Macs to run Windows on it. Used to save on hardware costs.
