Digital Technologies / Levels 5 and 6 / Digital Systems
Content description
Examine the main components of common digital systems, and how such digital systems may connect together to form networks to transmit data
Elaborations
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 include the central processing unit; external output components including speakers, projector, screen; and data and information storage components include 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 and radio waves are used to transfer 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
identifying different types of networks that allow data to be sent between digital systems, for example wired, wireless and mobile
