TRANSISTOR TRANSITION Vacuum tubes consist of three terminal devices called triodes The first point

TRANSISTOR TRANSITION Vacuum tubes consist of three terminal devices called triodes The first point contact transistormade use of the semiconductor germanium. Individual electronic components were soldered on to printed circuit boards. Integrated circuits placed all components in one chip, drastically reducing the size of the circuit and its components.
