A server is a computer or system that provides resources, data, services, or programs to other computers, known as clients, over a network. In computing, a server is a piece of computer hardware or software (computer program) that provides functionality for other programs or devices, called "clients". This architecture is called the client–server model. A single server can serve multiple clients, and a single client can use multiple servers. Servers act as data processors for professional and private use. Whether you work in an IT position or manage social media for a marketing firm, it's important to understand how servers function so you can access data through network applications. Once you know the basic workings of a server, you can utilize its processing capabilities through a local network or a virtual cloud computing platform. In this article, we explain the types of servers and how they function.
