A server is a powerful, central network computer. It makes its resources available to other computers. Functional and infrastructural network services are realized via the server.
Data that must be accessed by several people can be stored here.
However, the term server has a double meaning. One must distinguish between two different server definitions:
Hardware vs. Software
Definition server hardware
A hardware server refers to a computer that makes its resources available over a network. The server is a computer that is integrated into a computer network. A hardware server runs one or more software-based servers in addition to the operating system. Often, a hardware-based server is also referred to as a “host”.
Definition server software
A software-based server is a program that provides a special service. This service is used by other programs – also called clients – locally or via a network.
Servers are often the most powerful computers in a network. Thus, they have large hard disk capacities and a fast central processing unit (CPU).
In principle, servers can either operate in a closed (corporate) network or be accessible via the Internet.
