# Glossary (Version 8.4)

A small electronic device, consisting of a small chip and antenna, used for identifying and tracking products, animals and people.

A range of techniques used to quickly fabricate a scalemodel of a physical part or assembly using three-dimensional computer-assisted design (CAD). Construction of the part or assembly is usually done using 3D printing or additive layer manufacturing technology.

Technologies associated with reusing water or air after it has been treated to remove particles, gases and/or dissolved chemicals.

Digital representation of colour, displayed on pixels, through the use of varying amounts of red, green and blue light. By combining different amounts of each colour, many of the colours of the visible spectrum can be represented on screen.

A drawing that shows a relative relationship of elements or a form of objects using texture, colour, light, shade and tone (lightness or darkness of a colour). Rendered drawings are used, for example, in architecture to show what a building will look like or to show the form and shape of the body of a proposed car design. Rendering can be done by hand, or using computer software such as computer-aided drawing.

A statement used for declaring iteration and repetition in programming code. Usually a REPEAT statement continues to execute until some specified condition has been met, at which point the repetition ceases. Also known as a loop and implemented in many programming languages by terms such as ‘for’ or ‘while’. An example in Pascal may look like this:

      repeat        a := a + 1      until a = 10;

where the code will repeatedly print out a number and increase its value by 1 until the number reaches 10.

A material such as metals, plastics and timber that is usually firm and not easily bent or curved unless heat, pressure or force is applied.

In Design and Technologies, this includes technologies, energy, time, finance and human input.

A practice of identifying potential risks in advance, analysing them and taking precautionary steps to reduce/curb the risk. Risk management involves risk identification, analysis, response planning, monitoring, controlling and reporting.
