Arvutiserveri

Arvutiserveri, often referred to simply as a server, is a computer or a system that provides resources, data, services, or programs to other computers, known as clients, over a network. Servers are essential components of modern computing infrastructure, enabling a wide range of functionalities from sharing files and printers to hosting websites and managing complex applications. The term "server" can also refer to the software that runs on such a machine to provide these services.

Servers are typically designed for reliability, performance, and continuous operation. They often possess more powerful hardware than standard personal computers, including faster processors, larger amounts of RAM, and more robust storage solutions. This enhanced capability allows them to handle multiple client requests simultaneously and efficiently.

There are various types of servers, each specialized for a particular task. Common examples include web servers that host websites, file servers that store and manage shared files, mail servers that handle email communication, database servers that manage databases, and game servers that facilitate online multiplayer gaming.

The relationship between a server and its clients is defined by the client-server model. In this model, clients initiate requests for services or data, and servers respond by fulfilling those requests. This architecture is fundamental to the internet and most local area networks, allowing for centralized management of resources and information.
