Elaboration ACTDIK014

describing digital systems as having internal and external components that perform different functions, for example external components for inputting data including keyboard, microphone, stylus; internal processing components including the central processing …

Elaboration (1) ACTDIK014

explaining how data may be transmitted between two digital systems in different ways, for example that wires or cables are used in wired networks to transfer data from one digital system to another, and radio waves are used to transmit data in wireless …

Elaboration (2) ACTDIK014

investigating how the internal and external components of digital systems are coordinated to handle data, for example how a keyboard, central processing unit and screen work together to accept, manipulate and present data and information

Elaboration (3) ACTDIK014

investigating how emerging digital systems work, for example using an augmented reality app (or blended reality) and considering how images of real-world objects can be blended with computer-generated information to produce a virtual reality

Elaboration ACTDIK015

recognising that digital systems represent all types of data using number codes that ultimately are patterns of 1s and 0s (called binary digits, which is why they are called digital systems)

Elaboration (1) ACTDIK015

explaining that binary represents numbers using 1s and 0s and these represent the on and off electrical states respectively in hardware and robotics

Elaboration (2) ACTDIK015

recognising that the numbers 0, 1, 2 and 3 could be represented by the patterns of two binary digits of 00, 01, 10 and 11

Elaboration (3) ACTDIK015

representing whole numbers in binary, for example counting in binary from zero to 15, or writing a friend’s age in binary

Elaboration (4) ACTDIK015

exploring how division by two can be used as a technique to determine the binary representation of any whole number by collecting remainder terms

Elaboration (5) ACTDIK015

representing the state of an object in a game as active or inactive using the respective binary values of 1 or 0

Elaboration ACTDIP016

using digital systems to validate data, for example setting data types in a spreadsheet to make sure a date is input correctly

Elaboration (1) ACTDIP016

selecting and using peripheral devices suitable to the data, for example using a data probe to collect data about changing soil temperatures for plants, interpreting the data and sharing the results as a digital graph

Elaboration (2) ACTDIP016

recognising the difference between numerical, text and date formats in spreadsheets

Elaboration (3) ACTDIP016

using software to automate calculations to help with interpreting data, for example using functions to make arithmetic calculations using multiple cells and summing cell ranges

Elaboration (4) ACTDIP016

acquiring data from online sources by narrowing the focus, for example filtering data using provided options or performing queries using advanced search functions

Elaboration (5) ACTDIP016

using data visualisation software to help in interpreting trends, for example uploading data to a web application and building a visualisation of the dataset

Elaboration ACTDIP017

checking existing solutions to identify features that are transferable to new but similar digital solutions, for example identifying if there are any similarities (such as user age and special requirements) between an existing game and a new game to be …

Elaboration (1) ACTDIP017

investigating characteristics of user interfaces that are common for particular types of problems, for example, touch screens – many people respond more intuitively than when using a keyboard or stylus; and the consistent placement of symbols helps with …

Elaboration (2) ACTDIP017

using and interpreting data, establishing the root cause of a problem, for example using an annotated diagram to identify omissions, duplications or mismatches of data

Elaboration (3) ACTDIP017

describing in simple terms the nature of a problem and what a solution needs to achieve, for example what need the problem is associated with, who the solution is needed for, what data are needed and what features the solution would need to include
