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.
