What is Server?
A computer that responds to requests from others — like the kitchen of a restaurant.
// Explanation
A server is simply a computer configured to receive and respond to requests from other devices. It can be physical (a machine in a datacenter) or virtual (a portion of a larger machine). Web servers serve pages, database servers store information, mail servers send emails. When you open cual.ai, a server somewhere in the world responds to your request in milliseconds.
// Example
When you type cual.ai in your browser, your phone sends a request to a Vercel server in some datacenter, which responds with the page's HTML.
