What is Internet?

Internet is nothing else then a global network of interconnected computers. These interconnected computers allows peoples and devices to communicate with each other and share the data and information with each other. Internet works by using the protocols like TCP / IP to transmit the data between servers, computers and other devices.

How does the Internet Works

So the Internet works by connecting billions devices with each other through a system of networks using TCP / IP Protocols. So here is a complete process of How Internet works.

  1. Devices connect to the Internet

Our devices connect to the internet using

  • Wi-Fi (through a router and modem)

  • Mobile data (4G,5G)

  • Ethernet (wired connection)

  1. Data is broken into packets

When we open a website data is broken into small packets that travels independently across the internet.

  1. Data Packets travels through various devices

Data packets travels in the internet through various devices like

  • Routers – Direct packets across networks.

  • Switches – Transfer data within a local network.

  • Servers – Store websites, apps, and online services.

  1. Servers Process the Request

When we visit a website our data is sent to the web server that process the request and sends back to us the necessary data.

5. Packets are Reassembled

Once the data reaches to our devices , our browser reassembles the data packets and display us the website or the content.

  1. Continuous Two way Communication

This process happens continuously while browsing, streaming, gaming, or using online services, ensuring smooth communication.
