A network of networks
1 · Learn
The internet connects many networks. The web is one service that uses the internet to share linked pages. Other services can use the internet without being web pages.
A website address helps a browser request a page. An attractive page is not proof that its information is true or that a person on it is who they claim to be. Ask an adult before unfamiliar browsing.
2 · Worked example
I distinguish the school network from the wider internet. A document shared inside school does not have to be a public web page.
3 · Your turn
Are the internet and the web exactly the same thing? Explain simply.
Check your answer
No. The internet connects networks; the web is a service of linked pages that uses those connections.
4 · Apply your learning
With an adult, sort paper examples into local sharing and using an internet service. Discuss cases that could work in either way.
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.
