A device is a type of node. It is a physical resource and has the power to perform computations. Artifacts and components can be deployed to a device and typically rely upon services offered by the device to carry out their work. A device may be composed of other devices as part of a hierarchy of nested devices.

Explanation

A device is a physical resource that carries out the work of a system. When a device is purchased it typically arrives in a box, and requires unpacking. The device offers services to artifacts and components that are deployed upon it. A device can be a node in a hierarchy of parts, itself being a part of another device or owning other devices as parts.
