The CIM_WatchDog class described in Table 3-12 represents a timer that is implemented in system hardware. The watchdog feature allows the hardware to monitor the state of the operating system, BIOS, or a software component installed on the system.

The CIM_SoftwareFeature class shown in Table 3-31 defines a particular function or capability of a product or application system. This class is intended to be meaningful to a consumer, or user of a product, rather than to explain how the product is built or packaged. When a software feature can exist on multiple platforms or operating systems (for example, a client component of a three-tiered client/server application might run on Windows NT), a software feature is a collection of all the software elements for these different platforms. The users of the model must be aware of this situation because typically they will be interested in a subcollection of the software elements required for a particular platform.
