Technology layer active structure elements

The main active structure element for the Technology Layer is the node. This element is used to model structural entities in this layer. It strictly models the structural aspect of a system: its behavior is modeled by an explicit relationship to the behavior element.

A technology interface is the (logical) location where the technology services offered by a node can be accessed by other nodes or by application components from the Application Layer.

Nodes come in two flavors: device and system software. A device models a physical computational resource, upon which artifacts may be deployed for execution. System software is an infrastructural software component running on a device. Typically, a node consists of a number of sub-nodes; for example, a device such as a server and system software to model the operating system.

The inter-relationships of components in the Technology Layer are mainly formed by the communication infrastructure. The path models the relation between two or more nodes, through which these nodes can exchange information. The physical realization of a path is modeled with a network; i.e., a physical communication medium between two or more devices (or other networks).

Summary
A communication network represents a set of structures and behaviors that connects computer systems or other electronic devices for transmission, routing, and reception of data or data-based communications such as voice and video.
A device is a physical IT resource upon which system software and artifacts may be stored or deployed for execution.
A node represents a computational or physical resource that hosts, manipulates, or interacts with other computational or physical resources.
A path represents a link between two or more nodes, through which these nodes can exchange data (or material).
System software represents software that provides or contributes to an environment for storing, executing, and using specific types of entities, components, and objects that have a specific business purpose and are deployed on it in the form of artifacts.
An aggregate of two or more nodes that work together to perform collective technology behavior.
A technology interface represents a point of access where technology services offered by a node can be accessed.
