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:

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.
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.
Students explore aspects of animal adaptation prior to applying their knowledge to construct their own digital creature using littleBits electronic sets.
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.
Students explore different types of peripherals used every day to identify the data transmitted. A peripheral is an auxiliary device, such as a keyboard, that connects to and works with another device, for example a computer.
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.
