Q.The microprocessor, which made the personal computer possible, is the main technology of which generation of computers? (A) First generation
(B) Second generation
(C) Third generation
(D) Fourth generation

Each generation is defined by its main switching technology; the microprocessor placed the whole CPU on a single chip and belongs to one specific generation. …

The generations are defined by their core technology: first (vacuum tubes), second (transistors), third (integrated circuits), fourth (microprocessors), fifth (artificial intelligence).

(A) First generation used vacuum tubes — incorrect.

(B) Second generation used transistors — incorrect.

(C) Third generation used integrated circuits (ICs) — incorrect. …

Students sometimes confuse the integrated circuit (third generation) with the microprocessor (fourth generation) — the IC combined many transistors on a …
