Server
The term server has its origin from the English word "to serve”. The server is therefore a servant that provides services and resources. It makes the services and resources available to the so-called clients which can be programs, such as the browser, or devices. A server can perform various tasks. For example, it serves as a mail server in relation to e-mail services. There are two types of servers: hardware-based servers as well as software-based servers. A hardware-based server is a computer that is connected to a physical network. It runs a virtual server as the operating system. In a software-based server, this program communicates with the client program. Software-based servers therefore also run on hardware-based servers.
