A server is a specialized computer or software system that provides data, services, or resources to other devices — known as clients — over a network. In the context of the web, when you request a website through your browser, that request is sent to a web server, which retrieves or generates the necessary files (like HTML, CSS, JavaScript, or PHP-generated pages) and sends them back to your browser to display. Servers are designed to run continuously, handle multiple simultaneous requests, and manage tasks like hosting websites, storing files, processing emails, or serving apps. They’re the behind-the-scenes engine that powers much of the internet, from small blogs to massive social networks.
