In classical computer technology, the interconnection of computers to increase computing power played an important role. The approach of such an interconnected system could be focused on data management and access optimization. Depending on its characteristics, it was referred to as a data network or a performance network.
In the case of a computer network, the interconnection of several computers increased the computing power and optimized the capacity utilization.
In addition to the data network and the performance network, there is also the functional network, through which users can use programs and device functions of other network stations, the peripheral network, in which users share expensive peripheral devices, the load network and the availability network, which ensure optimal utilization of the computers and the provision of transmission capacities.
