Sita's grandmother lives in a village in Rajasthan. Sita lives in Mumbai. They cannot meet every day, but they can talk face-to-face using a video call on the computer! How is this possible? Because of the internet!
The internet connects computers all over the world. It is like a huge invisible road that carries information from one computer to another — whether they are in the same city or on the other side of the world.
The internet is a giant network that connects millions of computers around the world. Through the internet, computers can share information, send messages, and communicate with each other.

To use the internet, we need a special program called a browser. A browser is a program that lets us visit websites and view information on the internet.
Google Chrome — The most widely used browser. Has a colourful circle logo.
Mozilla Firefox — A popular browser with an orange fox logo.
Microsoft Edge — Comes built into Windows computers.
All browsers do the same job — they help you visit websites on the internet.
A website is a collection of pages on the internet about a particular topic or organisation. Every website has a unique address called a URL (Uniform Resource Locator).
www.google.com — Google's search website
www.ncert.nic.in — NCERT's official website for Indian students
www.youtube.com — YouTube's video website
You type the URL in the address bar at the top of the browser to visit a website.
Rule 1: Never share your full name, address, phone number, or school name with strangers online.
Rule 2: Always ask a parent or teacher before visiting a new website.
Rule 3: Do not talk to strangers on the internet.
Rule 4: If you see something that makes you uncomfortable, tell a trusted adult immediately.
Rule 5: Do not spend too much time on the internet — take breaks and play outside too!
