How the Internet Works

Server

A computer that listens for requests and sends back responses.

Definition

A computer that listens for requests and sends back responses. It runs software that serves web pages, processes data, or provides access to databases. It's always on, always connected, and waiting for someone to ask it for something.

Example

When you visit a website, your browser sends a request to a server. That server — which might be a physical machine in a data center or a virtual one in the cloud — sends back the files your browser needs to display the page.
