Glossary

abstraction

A process of reducing complexity to formulate generalised fundamental ideas or concepts removed from specific details or situation. For example, the idea that a cricket ball is a sphere in the same way that a soccer ball is, or the concept that data can be organised in records made up of fields irrespective of whether the data are numbers, text, images or something else.

accessibility

The extent to which a system, environment or object may be used irrespective of a user’s capabilities or disabilities. For example, the use of assistive technologies to allow people with physical disabilities to use computer systems, or the use of icons in place of words to allow young children to use a system.

aesthetics

A branch of philosophy dealing with the nature of art, beauty and taste. It is more scientifically defined as the study of sensory-emotional values, sometimes called judgements of sentiment and taste. Aesthetic judgement is concerned with the visual impact or appeal of a product or environment and is influenced by social, emotional and demographic factors.

algorithm/s

A description of the steps and decisions required to solve a problem. For example, to find the largest number in a list of positive numbers:

  • Note the first number as the largest.
  • Look through the remaining numbers, in turn, and if a number is larger than the number found in 1, note it as the largest.
  • Repeat this process until complete. The last noted number is the largest in the list.

An algorithm may be described in many ways. Flowcharts are often useful in visualising an algorithm.

algorithmic logic

The logic behind breaking down computing problems and information systems into step-by-step processes in order to solve problems or achieve specified outcomes. It involves sequencing and abstraction and leads to algorithmic statements.

analyse

Identify components and the relationship between them; draw out and relate implications.

assess

Make a judgement of value, quality, outcomes, results or size.

augmented reality (AR)

A technology that replicates, enhances or overlays extra information about the real-world environment, using computer-generated data such as global positioning systems (GPS), sound, videos and images. Examples include a car windshield with a heads-up display (HUD) that projects three-dimensional navigation information and virtual lanes; and a swimming telecast using a line to indicate the position of the record holder in relation to the actual swimmers in the race.

automate

In Digital Technologies, any process of transforming and manipulating data that does not require user intervention. For example, through the use of formulas in a spreadsheet, new sets of data can be processed and the results recalculated automatically, or a webcam can be turned on as a result of movement sensor input.

binary

A use of two states or permissible values to represent data, such as on and off positions of a light switch or the transistors in a computer silicon chip that can be in either the electrical state of ON or OFF.

Binary data are typically represented as a series of single digits referred to as binary digits (or bits) due to each taking on the value of either 0 or 1. The image below shows how a dashed line might be represented in binary.

biomimicry

An inspiration of functions found in nature for use and adaptation in the design of a product, service or environment or to solve human problems. For example, Velcro fastening was inspired by small hooks on the end of burr needles. Termite mounds that maintain a constant temperature through air vents inspired architects to design cooling for buildings.

bitmap

Mapping something to bits (binary digits 0 and 1). It is most often used in reference to graphics or images (but can be other forms of media). For a bitmapped graphic, each ‘dot’, or pixel, of the graphic is represented by a number giving the colour of the pixel. .bmp, .gif or .jpeg files are graphics represented as bitmaps (as opposed to vector graphics). If a graphic were stored or displayed using only 1 bit per pixel, it would be purely black and white (1 for black and 0 for white). If it were 2 bits per pixel, it could represent four ‘colours’ (typically greyscale colours). Using 24 bits per pixel gives over 16 million (224) different colours.

branching

Making a decision between one of two or more actions depending on sets of conditions and the data provided. For example, in testing whether a light works, the following algorithm uses branching:

carbon footprint

The environmental impact of an individual or organisation’s operation, measured in units of carbon dioxide. It includes primary emissions (the sum of the direct carbon dioxide emissions of fossil fuel burning and transportation such as cars and planes) and secondary, or indirect, emissions associated with the manufacture and breakdown of all products, services and food an individual or organisation consumes.

characteristics

A set of distinguishing aspects (including attributes and behaviours) of an object, material, living thing, system or event.

In Design and Technologies, the qualities of a material or object usually detected and recognised by human senses such as its colour, taste, texture, sound (for example, crunch of bread) and smell. The term also may relate to the form of a material, for example, ‘corrugated’ cardboard. These qualities are used by humans to select suitable materials for specific uses, for example, because they are appealing or suitable for their purpose. The characteristics of materials usually determine the way people work with the materials. Also see properties.

In Digital Technologies, for example, the characteristics of a stored digital graphic may be the colour depth (maximum number of colours represented), the resolution (number of pixels per area, or height and width) and the compression used.

client

A customer (sometimes known as a client, buyer, or purchaser) is the recipient of a good, service, product, or idea, obtained from a seller, vendor, or supplier, for a monetary or other valuable consideration.

codec

A piece of software that encodes or decodes digital audio-visual material, usually to allow it to be stored or transmitted in a compressed format. For example, the MP3 format compresses audio data and requires an MP3 codec (usually available by default in audio programs) to be read and played by a computer. Codecs can be downloaded or purchased and installed as plug-ins to most applications to extend the media capabilities of software. Also see compression.

codes of conduct

A code of conduct is a set of rules outlining the social norms and rules and responsibilities of, or proper practices for, an individual, party or organisation.

components

Parts or elements that make up a system or whole object and perform specific functions. For example, the major components of a car include: a chassis (holds everything on it); an engine (to convert energy to make a car move); a transmission (including controlling the speed and output from the engine and to rotate the wheels); a steering system (to control the direction of movement); a brake system (to slow down or stop); a fuel delivery system (to supply fuel to the cylinders); an exhaust system (to get rid of gases) and an electrical system (for operating wipers, air conditioning, etc.).

Similarly, the components of a computer system may be a central processing unit (chips that follow instructions to control other components and move data); memory chips and a hard disk (for storing data and instructions); a keyboard, a mouse, a camera and a microphone (to input instructions and data for the central processing unit); a screen, a printer and speakers (to output data); USB and ethernet cards (to communicate with other systems or components). Also see digital systems.

compression

Encoding information using fewer bits than the original representation to reduce file size. Common examples include:

  • .zip files, which can contain one or more files or folders that have been compressed
  • .jpg files in digital photography are produced by processing complete (lossless) data from a camera’s sensor through compressing (looking for redundant/unnecessary data) into a smaller file size
  • .mp3 files for audio, which compress an original audio source to reduce the file size significantly but still sound like an exact copy of the original.

data

In Digital Technologies data refers to, discrete representation of information using number codes. Data may include characters (e.g. alphabetic letters, numbers and symbols), images, sounds and/or instructions that, when represented by number codes, can be manipulated, stored and communicated by digital systems. For example, characters may be represented using ASCII code or images may be represented by a bitmap of numbers representing each ‘dot’ or pixel.

database

A collection of data organised by records and fields that can be easily stored, accessed, managed and updated. Each discrete piece of data to be stored is represented by a field (for example, song title, song artist or bank account number, date of transaction); and values in the fields that are associated with an entity (for example, a song, a bank transaction) are a record. Interaction with a database usually takes place through a user interface designed specifically for the structure and use of the data stored in it.

decompose

To separate a complex problem into parts to allow a problem to be more easily understood. For example, to create an interactive story, one can decompose the problem to a list of characters and their characteristics (for example, clothing), the actions of the characters, the backdrops and the sequence of scenes with reference to which characters, actions and backdrops are involved in each scene. Decomposition may be represented in diagrams.

desk checking

A method used by a human to check the logic of a computer program's algorithm to reduce the likelihood of errors occurring. This may be done on paper, using a diagram, or mentally trying a sample of typical inputs to see what the outputs would be. For example, to desk check a branching statement {IF age >65 THEN ‘retire’ ELSE ‘keep working’}, the values for age of 64, 65 and 66 could be tried to show that 64 and 65 would result in ‘keep working’ and 66 in ‘retire’ so that it could be decided if the statement worked as intended.

structured English

The use of the English language to describe the steps of an algorithm in clear, unambiguous statements that can be read from start to finish. The use of keywords such as START, END, IF and UNTIL provides a syntax similar to that of a programming language to assist with identifying logical steps necessary to properly describe the algorithm.

An example of the use of structured language can be demonstrated using the following problem:

Description of the problem: Describing the decision a person makes about how to get to a destination based on the weather and the distance from their current location to their destination.

ELSE IF it is less than 10km to the destination THEN

Ride a bicycle

ELSE

Catch the bus
