What is an ISP?
An ISP is a company that provides users with access to the internet. They do this by maintaining a network of interconnected computers and servers that are connected to the global internet infrastructure. When you sign up for internet service with an ISP, you’re essentially renting a connection to their network, which allows you to access the internet and all its resources. ISPs can be thought of as the “on-ramps” to the internet, providing the necessary infrastructure and services to connect users to the global network.
How do ISPs Work?
ISPs work by maintaining a network of servers, routers, and other equipment that are connected to the global internet infrastructure. When you send a request to access a website or online service, your device sends a signal to the ISP’s network, which then forwards the request to the destination server. The destination server then sends the requested data back to the ISP’s network, which forwards it to your device. This process happens rapidly, often in a matter of milliseconds, allowing you to access the internet and its resources quickly and efficiently.
