How ISPs Provide Internet?

ISPs maintain large data networks that are connected to larger internet infrastructures, including regional or national backbones.

When you request a website, stream a video, or play a game online, your data travels through the ISP’s network, eventually reaching its destination and returning with the requested content.

Here is a simple process that shows how an ISP provides internet connectivity.

Step 1. ISPs build and maintain physical infrastructure (cables, fiber optics, towers) to connect users to the global internet.

Step 2. Assign unique IP addresses to devices, enabling data transmission between networks.

Step 3. Use internet protocols like BGP (Border Gateway Protocol) to route data efficiently across the internet.

Step 4. Translate domain names (e.g., google.com) into IP addresses via DNS (Domain Name System).

Step 5. Manage network traffic to prevent congestion, sometimes prioritizing or throttling specific services.
