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 unit; external output components including speakers, projector, screen; and data and information storage components including cloud and external devices
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 or mobile networks
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
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
