What is the generation of computing known for the introduction of electronic components that could maintain exactly two states?

The second generation of computing introduced transistors, which replaced vacuum tubes and allowed for smaller, more efficient, and more reliable systems. While transistors also represent binary states, they were not the introduction of electronic components maintaining two states; that milestone was achieved during the first generation.

The third generation of computing saw the advent of integrated circuits, which further miniaturized components and enhanced processing power. Integrated circuits still operated on the principle of binary states but did not mark the initial introduction of such electronic components, a hallmark of the first generation.

The fourth generation of computing is defined by the development of microprocessors, which encapsulate millions of transistors on a single chip. Although these devices also work with two states, they represent a later evolution in computing technology rather than the original introduction of electronic components maintaining two states.
