A physical IT resource upon which system software and artifacts may be stored or deployed for execution. A device represents a physical IT resource with processing capability. It is typically used to model hardware systems such as mainframes, PCs, smartphones, or routers. It can also be used to model virtualized hardware. Usually, devices are part of a node together with system software. Devices may be composite; i.e., consist of sub-devices. The name of a device should preferably be a noun phrase referring to the type of
hardware; e.g., “IBM System z mainframe”.
