What is the Internet?
The internet is a giant global network of millions of computers all connected together. It lets computers share information with each other — no matter where in the world they are!
How Does it Work?
When you type a website address (URL) into your browser, here's what happens:
- 1️⃣ Your computer asks a DNS server — "Where is this website?"
- 2️⃣ The DNS replies with the website's IP address (like a home address for computers).
- 3️⃣ Your computer contacts the web server at that address and says "Please send me this page!"
- 4️⃣ The server sends back the website files (HTML, CSS, images).
- 5️⃣ Your browser reads those files and shows you the webpage!
Cables and Wireless
Data travels across the internet through undersea cables, fiber-optic cables, and Wi-Fi. Information moves as pulses of light through glass fibers — nearly at the speed of light!
Think of the internet like a postal system. Your computer writes a letter (request), sends it through a network of roads (cables), and a web server reads it and sends a letter back — all in less than a second!
