Hack

A term associated with an any change not approved by the manufacturer or developer that makes the device do something it was not initially intended to do. For example, with software updates and modifications users can make their Xbox gaming console more of a media center. Because these types of modifications are not supported by the developer hacks such as these will also often void warranty or not allow you to get support from the manufacturer.
