Any technology can be divided into four key components:
Hardware The physical structure or logical layout, plant or equipment of machine or contrivance. This is the means to carry out required tasks of transformation to achieve purpose or goals. Hardware therefore refers not only to particular physical structure of components, but also to their logical layout.
Software The set of rules, guidelines, and algorithms necessary for using the hardware (program, covenants, standards, rules of usage) to carry out the tasks. This is the know-how, which means how to carry out tasks to achieve purpose or goals.
Brainware The purpose (objectives and goals), reason and justification for using or deploying the hardware/software in a particular way. This is the know-what and the know-why of technology. That is, the determination of what to use or deploy, when, where and why. These three components form the technology core. The components of the technology core are co-determinant, their relations circular and mutually enhancing. The interdependence among the three components is well illustrated in the example of automobile as technology: A car consists of its own physical structure and logical layout, its own hardware. Its software consists of operating rules of the push, turn, press, etc., described in manuals or acquired through learning. The brainware is supplied by the driver and includes decisions where to go, when, how fast, which way and why to use a car at all. Computers, satellites or the Internet can be defined in terms of these above three dimensions. Any information technology or system should also be clearly identifiable through its hardware, software and brainware.
Technology Support Net TSN is a network of flows: materials, information, energies, skills, laws, rules of conduct that circulate to, through and from the network in order to enable the proper functioning of the technology core and the achieving of given purpose or goals. Ultimately, all the requisite network flows are initiated, maintained and consumed by people participating in the use and support of the use of a given technology. They might similarly and simultaneously participate in supporting many different technologies through many different TSNs. Sameer Kumar wrote that TSNs can be intermeshed into larger hyper networks, thereby revealing important complementary, competing and collaborating technologies. The relationship between the technology core and its requisite TSN is that of mutual enhancement and codetermination. Every unique technology core gives rise to a specific and requisite TSN and thus to a specific set of relationships among people. Ultimately, the TSN can be traced to and translated into the relationships among human participants: initiators, providers and maintainers of the requisite flows in cooperative social settings. In this sense, every technology is a form of a
social relationship brought forth from the background environment. The following example describes the various social relationships among people caused by technology support net. As for the automobile technology, its TSN consists of an infrastructure of roads, bridges, facilities and traffic signals, but also of maintenance and emergency services, rules and laws of conduct, institutions of their enforcement, style and culture of driving behavior, etc. A large number of people have to be organized in a specific and requisite pattern in order to enable cars to function as technology. Moreover, technology and its four components could also be defined from the vantage point of its own user or observer, not in a context-free or absolute sense. In other words, roads, bridges and traffic signals can be technologies themselves, with their own hardware, software, brainware and support nets. For example, traffic lights are a part of the TSN of an automobile, but their own hardware can be driven by their own software (a computer-controlled switching program or schedule) and brainware (purposes of safety, volume and flow control, and interaction with pedestrians). This technology core has its own support net of electricity, signal interpretations and car traffic. So the traffic light is a technology of its own. Similarly, a piece of software from some technology can itself become viewed as technology, in order to achieve specific business purposes or goals with its own hardware, software, brainware and TSN. == Functions of technology ==
