Show answer & explanation
Correct answer: D
Correct sequence: Vacuum tubes, Transistors, Integrated circuits, Microprocessor.
First generation — Vacuum tubes: Large electronic valves used in early computers; produced a lot of heat and were bulky.
Second generation — Transistors: Smaller and more reliable than vacuum tubes; reduced size and power consumption.
Third generation — Integrated circuits: Multiple transistors and components fabricated on a single chip, greatly increasing performance and compactness.
Fourth generation — Microprocessor: Central processing unit placed on a single integrated circuit chip, enabling personal computers and modern architectures.
Therefore the correct chronological order of the listed technologies is: vacuum tubes → transistors → integrated circuits → microprocessor.
