before adoption of microchips
On an old electronic board, there were basic functionalities, wired by the electronic engineer who needs it. These features are scattered on different cards, repeated each time, as needed.
a concept for the future for software engineering
Like other technology areas, component approach promises a significant advance in computer science. This is a concept still under development, whose practices are far from stable. Much of the intellectual and materials tools is still part of the research. However, the beginnings of uses and lessons learned from other fields of technology, can look forward with great hope.
