The term digital system refers to elements such as hardware, software and networks and their use. There may be many different components that make up one system; for example, a computer has a central processing unit, a hard disk, keyboard, mouse, screen etc. A peripheral device is a digital component that can be connected to a digital system, for example, a digital camera or printer.
Digital hardware and software components (internal and external) used to transform data into a digital solution. When digital systems are connected, they form a network. For example:

This 5-minute video explores the digital systems content descriptions within the Knowledge and Understanding strand of the Australian Curriculum. Find out more about what is expected at each level of the curriculum.
How to teach it
Students explore elements of a digital system, including hardware, software and some commonly used peripheral devices. They find out how these elements work together.
Students explore how electrical energy can be transferred and transformed in electrical circuits, using Makey Makey boards as the basis for experimentation and recoding of data.
Using four inventions from 1985, this lesson sequence explores the impact of innovation, supporting circumstances, how individuals contribute to change and the importance of addressing benefits as well as risks in the development of new systems.
Encryption of data is a means of protecting data, one example being the use of secret and public keys. This learning sequence examines cryptography and modern encryption methods for transmitting digital data securely.
Using the concept of transportation systems as a comparison, students develop understandings of the properties of networked systems and the underlying techniques used to transmit and validate data.
In this sequence students learn how the binary number system works and how we can represent text using binary numbers. They also learn one of the representations of the standard English alphabet used by computers. They look at how the same concepts apply to non-text data and analyse the effectiveness of some binary representation techniques to various types of data.
For the classroom
The Intel Galileo is a small, single-board computer designed for schools and hobbyists.
