Sharing through a network
1 · Learn
A network connects devices so they can exchange data. A school network may let approved computers use a shared printer or stored files.
Connections may use cables or wireless signals. A device can be on a local network without being connected to the internet. Access permissions still matter: connected does not mean allowed to open everything.
2 · Worked example
Two classroom computers send print jobs through the school network to one printer. Staff manage which users are allowed to print.
3 · Your turn
Does being connected to the same network give you permission to read another pupil's private file?
Check your answer
No. Network connection and permission are different. Follow the school's access rules.
4 · Apply your learning
Make a paper network with labelled device cards and string. Trace a pretend print job; do not change real network settings.
Adult guidance and safety
Use an adult-approved offline or school-managed application. Use invented data, original images and pretend identities. Paper models explain an idea but must be followed by suitable practical device work. Never enter real passwords or personal information in the working pad.
Open your writing and drawing pad
Write, draw or show your working. Use a mouse, pen or finger. This pad is not a submitted answer.
Not saved to your account. Download your drawing as PNG and your typed notes as TXT before leaving or refreshing. They are separate files. Do not enter private information.
Open a picture saved on this device to draw on it again. Opening replaces the drawing, but Undo can restore it. PNG only, up to 4 MB and 4096 × 4096 pixels. The picture stays in this browser; it is not uploaded. Paper lines in a saved picture become part of that picture.
Clear the drawing? Your typed notes will stay. You can undo this action.
Your pad is empty.
Open a UTF-8 TXT file from this device, up to 40 KB and 10,000 characters. It stays in this browser. Opening can be undone until you type again. Downloads keep a new copy; they do not change the file you opened.
Replace the notes on this page with the opened file? Download the current notes first if you want to keep them.
Typed notes are not submitted answers.
