............. is one of the gateway of internet.

An Internet Service Provider (ISP) is a company or organization that provides access to the Internet. It acts as the primary "gateway" because individuals, homes, and businesses cannot connect to the global internet infrastructure directly without an ISP. When you subscribe to an ISP (like Jio, Airtel, etc.), they provide you with the necessary routing, infrastructure, and access points to route your data traffic to the rest of the web.
