A novel system and network architecture unburdens the end users as a result of reduced complexity of the infrastructure used by said users. As a result of the omission of processors, operating systems and conventional software on the user side, the use of the IT is simplified and the infiltration of malware into the devices belonging to the end users is prevented. In addition, the new architecture makes it possible to set up secure and more efficient networks even with respect to IoT and Industry 4.0 as well as new business models and supports both the coexistence and the migration of the conventional technology to the new architecture.
