What is a Server?
A server is a computer system or software application that provides services, data, or resources to other computers (clients) over a network. In web hosting, servers store website files and deliver them to visitors' browsers when they request a web page.
How Does Server Work?
Servers operate on a request-response model where client devices send requests and the server processes them and returns the appropriate data. A web server receives HTTP requests from browsers and responds with HTML pages, images, scripts, and other assets. Servers run specialized software like Apache, Nginx, or IIS that handles these connections efficiently, often serving thousands of simultaneous requests.
The term server can refer to both the physical hardware and the software running on it. A single physical server can host multiple software servers, such as a web server, database server, and email server running simultaneously. In modern hosting environments, servers range from shared machines handling many small websites to powerful dedicated systems and distributed cloud clusters serving millions of users.
