In this section we will go through a long, but accelerated road that computer science traveled. From the great equipment that occupied enormous spaces, to the modern devices that we have today. It has become the fundamental lever of all sciences, allowing them to make huge changes in short periods of time. This section deals with concepts, definitions and history, including the pioneers and those who transform the computing concept on a daily basis. Each topic is treated with profound scientific rigor, but with the simplicity that all readers need, regardless of their knowledge degree in the field.
