Question

Which of the following statements are correct? A. The vacuum tubes were used in the internal circuitry of 1st Generation Computer. B. Transistor were used in the internal circuitry of 2nd Generation Computer. C. VLSI Technology were used for 4th Generation Computer. D. Integrated Circuits were used in the internal circuitry of 3rd Generation Computer. E. Medium scale Integration Technology used of 2nd Generation Computer.

• A. A, B and D only
• B. B, C and E only
• C. A, B, C and D only
• D. C, D and E only

Hint:

Computer generations: 1st vacuum tubes, 2nd transistors, 3rd integrated circuits, 4th VLSI technology.

Answer 1

The Correct Option is C

Concept:
Generations of computers are classified based on the major technology used in their internal circuitry.

Step 1: First generation.
First generation computers used vacuum tubes. \[ A \text{ is correct} \]

Step 2: Second generation.
Second generation computers used transistors. \[ B \text{ is correct} \]

Step 3: Fourth generation.
Fourth generation computers used VLSI technology. \[ C \text{ is correct} \]

Step 4: Third generation.
Third generation computers used integrated circuits. \[ D \text{ is correct} \]

Step 5: Medium scale integration.
Medium scale integration is not the main technology of second generation computers. Second generation is mainly based on transistors. \[ E \text{ is incorrect} \] Thus, the correct statements are: \[ A,\ B,\ C \text{ and } D \] \[ \therefore \text{Correct Answer is (C)} \]
