Digital technologies / Year 7 and 8 / Digital Technologies Knowledge and Understanding

Curriculum content descriptions

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

Elaborations
  • 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
General capabilities
  • Literacy Literacy
  • Critical and creative thinking Critical and creative thinking
  • ICT capability Information and Communication Technology (ICT) capability
ScOT terms

User interfaces,  Computers,  Transmission control protocols,  Internet,  Data security

Systems Thinking and AI applications

This lesson takes a systems thinking approach to understanding the place of artificial intelligence (AI) as a component within solutions to real world problems, such as predicting bushfire hotspots, spotting and monitoring animals in the wild, automated horticulture and agriculture, and early detection of medical issues.

Recognising AI

Use the tasks in this lesson to introduce concepts that underpin artificial intelligence (AI). The majority of the tasks are unplugged (do not require a digital device). Use the downloadable AI cards with your students to explore what they know about AI.

Anti-bullying AI

Sometimes we write and post things on social media in a hurry. Such posts can hurt people and even make them feel bullied. Wouldn't it be great if an Artificial Intelligence application could check our posts as we write them, and warn us if they were potentially hurtful?

Data bias in AI

Artificial intelligence can sometimes be biased to certain shapes or colours. When such AI systems are applied to situations that involve people, then this bias can manifest itself as bias against skin colour or gender. This lesson explores bias in AI, where it comes from and what can be done to prevent it.

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? ...
