What the internet actually is (network of networks) in Intro to Computing - Flowchart & Logic Diagram

Process Overview

The internet is a huge system made by connecting many smaller networks together. This flowchart shows how data travels through these networks to reach its destination.

This flowchart shows how data moves from a user's device through local and other networks via routers until it reaches the destination device.

Step-by-Step Trace - 8 Steps

Step 1: User device sends a data request (like opening a website).

Step 2: Check if the destination is inside the local network.

Step 3: Since the destination is not local, data is sent to the router.

Step 4: Router forwards data to another network.

Step 5: Check if data has reached the destination network.

Step 6: If not reached, data is forwarded to the next router.

Step 7: Once data reaches the destination network, it is delivered to the destination device.

Step 8: Process ends after data delivery.

This diagram shows the internet as a chain of connected networks and routers linking the user's device to the destination device.

Flowchart Quiz - 3 Questions

What is the first step when your device sends data over the internet?

A Router forwards data to another network

B Data reaches the destination device

C Sending data request from your device

D Data is delivered within the local network

Key Result

The internet works by connecting many smaller networks through routers, allowing data to travel step-by-step until it reaches its destination.
