Virtualization in computers refers to setting up an environment in which a complete computer (refered to as the guest machine) is installed on another computer (refered to as the host machine). The virtualization software acts as the hardware for the computer installed in its environment and passes the proper commands to the host computer to accomplish the task and then translating the results back to the guest computer.

Microsoft and VMWare provide virtualization programs. In addition if you are interested there is an opensource virtualiztion environment called virtualbox. I recommend this for someone who is trying virtualization out. Remember that you need licences for the operating system and software you install in the virtual environment. This is one of the reasons I recommend virtualbox because it works will with linux and you can download and install different versions of linux on it without a worry about licensing. It is also a good way to try out linux. Also the documentation on virtualbox is pretty good.
