๐ What is the Internet?
The Internet is like a giant network that connects computers all over the world. Imagine it like a huge system of roads connecting different cities. Instead of cars, information travels on these roads, from one computer to another! It's sometimes called 'a network of networks' because lots of smaller networks are all connected together to make one big network - the Internet!
๐๏ธ A Quick Look Back at the Internet's History
The Internet didn't always exist. A long time ago, in the 1960s, some smart people in the United States wanted a way for computers to share information even if some of the computers were damaged. They created a system called ARPANET, which was the start of the Internet we use today. Over time, more and more people and computers joined the network, and it grew into the amazing thing it is now!
๐ Important Ideas About the Internet
- ๐ฆ Packets: โ๏ธ Information is broken down into smaller pieces called packets, like sending a letter one page at a time. These packets travel separately and are put back together when they reach their destination.
- ๐ IP Address: ๐ Every device on the internet has a unique address, like your home address. This helps computers find each other.
- ๐ก Servers: ๐ข These are special computers that store information and send it to you when you ask for it, like a library with lots of books.
- ๐ Links: ๐ These are connections between different parts of the internet, like roads that connect different cities. Clicking on a link takes you to another page.
