The Technological Knowledge Strand Explanatory Papers Updated May 2010
Technological Systems
Abstract
The purpose of this explanatory paper is to explain understandings of componentry and processes as they relate to a technological system, clarify why and how components are selected and connected and how they allow technological systems to work the way they do. It presents the strand descriptor, the key ideas underpinning it, and illustrative examples of these from technology. This paper also suggests possible learning experiences.
Component descriptor
Technological systems are a set of interconnected components that serve to transform, store, transport, or control materials, energy, and/or information. These systems exist in the world as the result of human design and function without further human design input. Understanding how these parts work together is as important as understanding the nature of each individual part.
Technological system knowledge includes an understanding of input, output, transformation processes, and control, and an understanding the notion of the 'black box', particularly in terms of sub-system design. Understanding redundancy and reliability within system design and performance, and an understanding of the operational parameters of systems are also included. Specialised languages provide important representation and communication tools and are therefore included to support developing ideas of system design, development, maintenance, and troubleshooting.
