As an explanation

The biggest man-made Machinery had been a post-construction system until a few years ago, namely the global Telephone network. At the moment, the telephone network passes through a transition phase and proceeds in a further, even larger tracking system, Internetwithout this being aware of a wider public. The telephone network becomes or became a component of the Internet for a period of time as access technology, and thereby changes technologically and structurally fundamentally. This process is in Germany and other Western Industry already largely completed. By the end of 2018 Deutsche Telekom the fixed network, i.e. in particular also the technical infrastructure for telephone and data remote connections, throughout Germany on the Internet-based IP telephony and all connections on VDSL– Technique changed.^[1] For normal Network-Telephone customers only changed that their previous Network telephone now, possibly DSL routers is connected with the same or extended functionality.

The Internet is an example of the flowing transitions from message technology to Information. On the one hand, post-processing systems are often important components in the computer systems of technical and applied computer science, on the other hand, modern post-processing systems are often based on theories and methods of computer science and are in the core computer systems.
