ICT e società dell'informazione

[Autom. eng. transl.] Information technology today is not a topic for (only) technicians: over 4 billion people connected to the Internet are the digital world that joins the real world. Understanding how society has evolved and how it interacts with technology is no longer only technical, it is also sociology, politics, jurisprudence, psychology, philosophy and training. Each technological innovation is always accompanied by a social impact, initially limited, then gradually deeper. The importance of data was already known in the 1950s, when a one-ton closet was needed to store 5 Mb (3-4 mp3 tracks). Today in less than 5 grams we store 256 Gb. Think about what our smartphone can do compared to one of 10 years ago: much of the difference is there. The intent of the authors is to explain how modern technologies work to humanists, so that they can understand what is at the basis of the digitalization of society, what is expressed in it, what ethical problems it raises and what new pathologies it has brought out, new and worrying , such as the fashion of extreme selfies and many other new behavioral, psychic and physical pathologies. The issue of cyber security is also addressed: what is it, who are the perpetrators of cybercrimes, how they act and why. The technological aspects are illustrated in a simple way, without the need for technical preparation: what you need is among the pages of this manual. The hope is to involve and excite as many students as possible, because - even if they will not devote themselves to these issues in their future - if they have understood and disseminated them, it will be an important result.
