Australian Digital Technologies Curriculum:

Digital systems

A system that processes data in binary, made up of hardware, controlled by software, and connected to form networks.

Digital systems

Recognise and explore digital systems (hardware and software components) for a purpose (ACTDIK001)

Identify and explore a range of digital systems with peripheral devices for different purposes, and transmit different types of data (ACTDIK007)

Examine the main components of common digital systems and how they may connect together to form networks to transmit data (ACTDIK014)

Investigate how data is transmitted and secured in wired, wireless and mobile networks, and how the specifications affect performance (ACTDIK023)

Investigate the role of hardware and software in managing, controlling and securing the movement of and access to data in networked digital systems (ACTDIK034)

Systems

Systems incorporates how we build and use systems in all aspects of our lives.

Identify digital systems

Recognise and name digital systems.

Students can name digital systems (e.g. smart phone or laptop) that they interact with at home and school and recognise that it is a digital system.

Explore digital systems with purpose

Play with and use digital systems in meaningful ways.

Students can play (with guidance) and use different systems to explore what they do and how they work. They can match digital systems to specific purposes.

Identify digital systems

Recognise and name digital systems.

Students can identify a range of different digital systems, drawing on systems they know and their characteristics.

Explore digital systems with purpose

Play with and use digital systems in meaningful ways.

Students can differentiate between different systems, and describe the different roles each of these systems plays when they are in use. The range of systems students are interacting with regularly should begin to increase, and they should get some exposure to systems they may not have familiarity with through their regular use. Some digital systems have a single purpose, while others are far more flexible.

Peripherals and Components

Digital systems are made up of parts that perform different functions, and can be altered or enhanced with additional, external devices.

Students can understand that many systems allow for additional, external devices to be plugged into them through some kind of interface, and that these devices add to or otherwise alter the functionality of the system.

Peripherals and Components

Digital systems are made up of parts that perform different functions, and can be altered or enhanced with additional, external devices.

Students can explain how digital systems are made up of other parts e.g. tablets contain things like screens, batteries and processors that together make the device useful.

Specifications and Performance

How well digital systems perform tasks is dependent on the characteristics of the components of a system.

Students can explain how different specifications, such as RAM available, CPU/GPU, network media etc impact performance of a system. Since systems are made up of lots of parts, the overall performance of any system - whether stand-alone or networked - is dependent on the specifications of all of its components.

Managing Data

Data is stored on a physical medium that can be accessed through software.

Students can explain the principles of data management such as account privileges and linking accounts across services.

Networks

Networks describe how we connect devices together and use them to transmit data.

The content descriptions do not explicitly address Networks in band F-2.
Transmit Data

Sending information from one place to another.

Students can understand the general concept of data transmission - the idea that data can be sent (i.e. reproduced in another location) from one place to another, allowing it to be understood or accessed elsewhere. Technical understanding of how this occurs is learned at a later band level.

Forming Networks

Different systems can be connected to one another, allowing them to send information between them.

Students can describe how networks are formed by connecting separate devices together.

Transmit Data

Sending information from one place to another.

Students can describe how data is sent through a network, and how the data is transferred indirectly from the source to the destination, often through many other devices on its way to the end point. Different devices on the network contribute to this process in different ways.

Transmit Data

Sending information from one place to another.

Students can describe how data is transmitted through a network, and the technical solutions used to mitigate potential errors or problems the network may experience.

Forming Networks

Different systems can be connected to one another, allowing them to send information between them.

Students can explain how the design of networks is affected by many things, including the media used in their construction. They understand that networks can be wired, wireless or mobile, and some of the limitations, implications and benefits of each.

Transmit Data

Sending information from one place to another.

Students can epxlain the technical details of how modern networks determine how data moves from one location to another, such as how routers use IP addresses to direct packets through a network.

Security

Security is concerned with how we protect the data stored in and trasmitted by systems.

The content descriptions do not explicitly address Security in band F-2.
The content descriptions do not explicitly address Security in band 3-4.
The content descriptions do not explicitly address Security in band 5-6.
Data Security

Making sure the data can only be accessed by the people it is intended for.

Students can explain how the movement of data through networks creates a situation where it would be possible for that data to be accessed by another party. This creates a need for security to be factored into the network design, and students should understand the general principles of securing data.

Data Security

Making sure the data can only be accessed by the people it is intended for.

Students can describe some of the methods used to secure data in digital systems, such as encryption techniques, access permissions and security certificates / keys.

Data Access

How data is transferred between users/systems and which users are able to access it can be controlled by hardware and software.

Students can understand how and why managing data access is an important part of secure and reliable networks, and how software and hardware allow this to happen. This could include things such as file permissions to restrict access to sensitive data, and things such as Demilitarised Zones (DMZs) to protect data from unwanted access or unplanned loss.
