Internet, web and networks I · Lesson 01 / 10

Internet: a network of paths

A page seems to arrive whole. Discover the networks that make its journey possible.

Learning paths10 min

Let's discover together

  1. 1

    A network connects devices that exchange data using shared rules called protocols. The internet joins many independently managed networks; it is not one central computer.

  2. 2

    Wi-Fi connects your device to a nearby network. That network can work without internet access. A Wi-Fi symbol does not prove a distant page will respond.

  3. 3

    The web consists of resources accessed through URLs, usually with HTTP or HTTPS. The internet also carries other services. Browser and internet are not synonyms; a local page can open without an external connection.

  4. 4

    Data travels in units called packets. Routers forward packets between networks. Cables, radio, providers and equipment all play a part; a failure need not be in the site or your device.

Your investigation notebook

Read, predict and explain. Every lesson has Markdown notes to edit, download and optionally publish on GitHub. ZIPs contain starter material, not your browser edits.

YOUR MISSION

Distinguish the internet, the web and a local connection.

Now it's your turn

Discovery workshop

Observe before concluding

Luma can print over the home network, but a distant page will not open. Wi-Fi is still connected.
Build your answers and check when you are ready.
A moment to understand

Does this account alone identify the cause?

I need a hint

Return to the evidence: what was observed and what is still unknown?

Loading your journey…

Take it with you

Draw your device, a local network and a distant service. Mark known facts and use question marks for missing evidence; do not record personal IP addresses.

Every lesson can become your own record: code, notes or a practice plan. Saving a file to GitHub is optional and does not change your XP.
