A mainframe is the central data repository, or hub, in a corporation's data processing center, linked to users through less powerful devices such as workstations or terminals. The presence of a mainframe often implies a centralized form of computing, as opposed to a distributed form of computing.
In this context, a mainframe computer can be the host provider of services for the workstations attached to it. This does not mean that the host only has servers and that the workstations only have clients.. The server-client relationship is a programming model independent of this contextual usage of host..
