A server is a specialized computer or software system that provides resources, data, services, or programs to other computers, known as clients, over a network. Servers are designed to manage, store, process, and deliver information efficiently, enabling multiple users or devices to access shared resources such as files, websites, applications, or databases. Depending on their function, servers can take various forms, including web servers, file servers, mail servers, and database servers. They play a critical role in modern IT infrastructure, supporting everything from small business operations to large-scale enterprise systems.
