Curriculum content descriptions

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

  • explaining that networks have components that control the movement of data, for example routers, hubs, switches and bridges manage data traffic and that the characteristics of these components impact on the operation (speed and security) of networks
  • explaining how cellular radio towers (transceivers) and mobile phones work together to create mobile networks
  • comparing the reliability and speed of transmitting data through wireless, wired and mobile networks
  • recognising that there are different communications protocols for transmitting data in networks, for example hypertext transfer protocol (HTTP) is used for transferring web page files in a browser, file transfer protocol (FTP) is used for sending and receiving any files over a network and transmission control protocol/internet protocol (TCP/IP) is used for controlling file transfers over the internet

How do computers get hacked?

What are some examples of cyber crime? Watch this clip to find out how viruses, denial of service attacks (DDoS) and phishing scams work. What is a botnet? And how are they used by hackers to bring down websites? Most of the time computers get hacked because of simple mistakes users make. What can users do to better protect ...


How 'binary information' is communicated via the internet

Ever wondered how your photos, emails and messages get sent between devices? Watch as software engineer Tess Winlock explains what binary information is, and how it gets from one place to another. Can you explain what 'bits' are? How about 'bytes'? In the past, binary information was sent using physical systems like semaphore ...


What makes the internet run reliably?

Watch this clip to see software engineer Lynn Root and co-creator of the internet Vint Cerf explain what keeps the internet running reliably. When information is sent on the internet, it is broken down into packets that are able to take a number of routes to get from one computer to another. Why might this be important? ...

Curzon & Bell et al. review: Computational thinking

This article explores the concept of computational thinking within computer science learning and in relation to other learning areas. The authors assert that because of its focus on analysis, computational thinking is not only suitable for computation but also the development of systems-based on computation.

Booth Sweeney review: Systems literacy

This article explores how children’s innate understanding of systems can be developed through deliberate educational programs that support systems thinking. This can happen by encouraging students to identify patterns, consequences and feedback (loops) associated with social, environmental and economic problems; and by ...


Volmert et al. review: STEM learning

This report examines the similarities and differences in the understandings about STEM education between experts and the general public in some American states. The authors contend that one of the most interesting findings is the role of Science: the general public equates STEM as Science, whereas the experts view all STEM ...
