The term 'digitalization' evokes a wide range of reactions. On the one hand, there are visions of a better and fairer world in the future; on the other, there are fears of change and even fear of electronic machines. An attempt at a simple definition should help. Digitization is the conversion and presentation of information into files with the help of electronic information technology such as computers, cell phones, Internet applications and a wide variety of file databases. More or less unnoticed, digitized technology has become an everyday companion and part of modern society in recent decades. Further development is taken for granted; a modern society needs technological progress as a matter of course. The study is divided into four parts: general digitalization, digital learning and teaching, artificial intelligence and networking.
