What is it?
A global network infrastructure that links billions of computers and devices. It’s both a concept and a real, physical technology made of cables, servers and wireless signals.
Tech Understandability: Beginner
Simple One‑Sentence Definition
The Internet is a worldwide system of connected computers and devices that lets people share information and communicate.
Analogy or Comparison
Imagine a giant library mixed with a post office—endless shelves of information and a system for sending messages anywhere in the world.
Why it matters?
The Internet lets you read the news, watch videos, send messages and shop without leaving home. When you browse a website, your computer sends a request through physical cables or wireless networks, and the website’s data travels back to you. Without this network, many everyday conveniences—like video calls with family or online banking—wouldn’t exist.
Fun Fact
