Server.

A server is a hardware or software system designed to provide data, resources, services, or programs to other computers over a network. In the context of websites, a server is a powerful computer that stores your website's files and sends them to a visitor's browser whenever someone requests your web address. The name comes from what it does. It serves. You make a request by typing a URL into a browser. The server receives that request, retrieves the relevant files, and delivers them back to your device. That exchange happens in a fraction of a second and repeats every time any visitor anywhere in the world loads a page on your site. Servers are hardware or software devices that provide resources to other computers. In practice for most website owners, a server is a machine you never see or touch. It lives in a data centre managed by your hosting provider, connected to the internet at high speed, running around the clock. When you pay for web hosting, you are essentially renting space and processing power on one of those servers. There are different types of servers depending on what they are used for. A web server stores and delivers website files. A database server stores the content, user data, and dynamic information that a CMS like WordPress retrieves to build pages. A mail server handles email delivery. In a modern web application, several of these server types work together. The location and quality of the server your website is hosted on directly affects how fast your site loads. A server physically closer to your visitors responds faster. A server with more processing power handles more simultaneous visitors without slowing down.

Every website depends on a server. There is no alternative. Understanding what a server is helps you make better decisions about hosting, understand why your site might be slow, and ask the right questions when choosing where to host a project. When clients ask why their website is down, why pages load slowly, or why emails are not sending, the answer almost always starts with the server.
