## What Is the Internet?
The **internet** is a massive global network of computers and servers that are connected to each other. These devices communicate using standardized rules called **protocols**, allowing data to be sent and received worldwide.
In simple terms:
👉 **The internet is a network of networks.**
When you open a website, send an email, or watch a video, your device is communicating with other computers somewhere else in the world.

## A Brief History of the Internet
The internet did not start as a public service. It began in the late 1960s as a research project called **ARPANET**, funded by the U.S. government. Its goal was to create a reliable communication system between computers.
Over time:
* Universities joined the network
* Businesses adopted it
* The **World Wide Web (WWW)** was introduced in the 1990s
* The internet became publicly accessible
Today, billions of devices are connected globally.

## How Does the Internet Work?
At its core, the internet works by **sending data from one device to another**.
Here’s what happens when you visit a website:
1. You type a website address (URL) into your browser
2. Your browser asks a server where that website is located
3. The server sends the website data back to your browser
4. Your browser displays the page on your screen
All of this happens in **milliseconds**.

## What Is a Server?
A **server** is a powerful computer that stores websites, images, videos, and other online data.
When someone visits a website:
* The server delivers the requested files
* The user’s browser turns those files into a visible web page
Servers operate 24/7 to keep websites available at all times.

## What Is an IP Address?
Every device connected to the internet has an **IP address**, which is a unique numerical label (for example: 192.168.1.1).
Think of it as:
📍 **A digital home address**
IP addresses allow devices to find and communicate with each other accurately.

## What Is a Domain Name?
Because IP addresses are hard to remember, we use **domain names** like:
* google.com
* wikipedia.org
* jponthenet.blogspot.com
A system called **DNS (Domain Name System)** translates domain names into IP addresses so computers know where to connect.

## How Data Travels on the Internet
Data on the internet travels in small pieces called **packets**.
Each packet:
* Contains part of the information
* Knows where it’s going
* Can take different routes
Once all packets arrive, they are reassembled into the original message, image, or video.
This makes the internet fast and resilient—even if one route fails.

## What Is the World Wide Web?
The **World Wide Web (WWW)** is only one part of the internet.
* The internet = the infrastructure
* The web = websites and web pages
Other internet services include:
* Online gaming
* Cloud storage
* Messaging apps
