A server is a powerful computer designed to store, process, and deliver data to other computers (called clients) over a network. Web servers host websites, making them accessible through browsers. Database servers store and manage information. Email servers handle message delivery. Servers typically run continuously in secure, climate-controlled facilities. Government services like CanuckDUCK rely on servers to store user data, forum posts, and glossary content, serving this information to users when requested. Servers require maintenance, security updates, and backup systems. Many organizations now use cloud computing, where server capacity is rented from providers like Amazon, Google, or Microsoft rather than operating physical servers.
