Answer:
A transistor is a semiconductor capable of amplifying and rectifying an electrical current. Transistors are present in the vast majority of electrical devices, in electronic circuits or microchips. Thus, the smaller the transistors, the smaller the electronic devices can also be, and the smaller these, the more maneuverable they can be for humans, who can handle them without major difficulties. This means that the smaller the transistors, the greater technological advances aimed at improving the life of society can be launched on the market.
