B. 2$^{nd}$ Generation	II. Semiconductor memory
C. 3$^{rd}$ Generation	III. Magnetic core memory
D. 4$^{th}$ Generation	IV. Electromagnetic relay memory

• A. A-IV, B-III, C-II, D-I
• B. A-IV, B-II, C-III, D-I
• C. A-IV, B-III, C-I, D-II
• D. A-III, B-I, C-IV, D-II

Hint:

To remember the flow of components: Relays/Vacuum Tubes (1st) $\rightarrow$ Transistors/Magnetic Core (2nd) $\rightarrow$ ICs/Minicomputers (3rd) $\rightarrow$ Microprocessors/Semiconductors (4th).

Answer 1

The Correct Option is C

Concept: Computer evolution is categorized into generations based on the primary electronic component and memory technology used during that era. Each leap in generation resulted in smaller, faster, and more efficient hardware.

Step 1: Matching Early Generations.

• 1$^{st$ Generation (A):} Early computers like ENIAC used vacuum tubes and Electromagnetic relay memory (IV) for storage and processing logic.
• 2$^{nd$ Generation (B):} Transistors replaced vacuum tubes, and the primary memory technology shifted to Magnetic core memory (III).

Step 2: Matching Modern Generations.

• 3$^{rd$ Generation (C):} This era saw the introduction of Integrated Circuits (ICs). The "Mini computer" (I) also became prominent during this time as computers became small enough for departmental use.
• 4$^{th$ Generation (D):} Characterized by VLSI (Very Large Scale Integration) and microprocessors, this generation adopted Semiconductor memory (II) (RAM/ROM) as the primary storage medium.

Step 3: Conclusion.
Mapping these pairs results in: A-IV, B-III, C-I, D-II. This corresponds to Option (3).
