How does Internet work ?

Hello, Everyone in this article we are going to understand that how does internet works ?

In general, We all know the word “Internet” means ‘Inter connected network’. It can be treated as a giant network around the world i.e. in simple way ‘network of networks’. On the other hand, Internet and Web or World Wide Web are different because ‘Web is a subset of Internet’ and we can define Web as collections of all the websites or HTML pages stored in billions of devices.

Trust me the whole game is sharing data from one device to another device over the internet. We only have to understand that how data is shared between different devices on the internet.

Client Server Model

Many internet services follow a client-server model. Clients, such as web browsers, email clients, user, laptop, computer, sends request to the server. Servers receive these requests, process them, and send back the requested information as response packets.

Here is 5 Steps

1. Breaking Data into Packets

When you send data (like an email or request a webpage), it’s broken into small chunks called packets. Each packet contains:

• A piece of the data.

• The destination address (where it’s going).

• The source address (where it’s from).

2. Sending Packets to a Network

Your device sends these packets to a local network (like Wi-Fi or mobile data), which connects to your Internet Service Provider (ISP). The ISP acts as the first gateway to the internet.

3. Traveling Across the Internet

Packets travel through a series of routers.

• Routers are like traffic managers, directing packets toward their destination using the most efficient path.

• These paths include cables, fiber optics, and even undersea internet cables connecting continents.

Each packet might take a different route to reach its destination, but they are reassembled in order at the end.

4. Reaching the Destination

The packets arrive at the target server (e.g., Google’s server if you’re visiting Google). The server processes the request and sends a response back to you in the form of new packets.

5. Reassembling Data

When the packets return to your device, they are reassembled to form the data you requested (e.g., a webpage, video, or email). This happens so quickly that it feels instantaneous.

Key Components of the Internet

1. IP Addresses: Every device and website has a unique identifier, like a phone number, ensuring data reaches the right place.

2. DNS (Domain Name System): It translates website names (like www.google.com) into IP addresses that computers understand.

3. Protocols (HTTP, TCP/IP): Rules that ensure data is sent and received correctly.

In Simple Terms

The internet works by breaking data into packets, sending them across networks, and reassembling them at the destination. It’s like sending a puzzle through the mail, with each piece taking its own path but arriving at the same place to form the complete picture!
