Computer networks
Examine how digital systems connect and transmit data — text, images, sound and video sent by cable or wirelessly (e.g. USB, Bluetooth, Wi-Fi, mobile networks) through home or school networks with routers and servers — so they can share data and resources, noticing that larger files take longer to send
Lesson
Set out your lesson
“Computer networks means practising the idea at the table with a simple screen-free or sandbox check. We will demo once, then your child tries.”
Bring to the table
- Device photo cards or a labeled computer sketch
- Sticky notes for part names
Extra for the adult
Worked example. The keyboard is an input — it sends letters into the computer.
Optional challenge. For Computer networks, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Computer networks, not mastery.

Check understanding
- Send a photo from a tablet to a printer or another device (by cable or wirelessly) and describe the path the data took
- Draw a diagram of the school or home network showing devices, the router and wired and wireless links, and explain how it lets devices share data and resources
- Compare sending a text message, a photo and a short video and explain which takes longest and why, and compare a wired and a wireless connection
“Can your child explain how a photo gets from a phone to the printer or to Grandma's tablet — and why a video takes longer to send than a text?”
