1.  
Match the followingMatch the generation with its switching device:
P. First Q. Second R. Third
1. Integrated circuits 2. Vacuum tubes 3. Transistors

Correct Answer: C [P-2, Q-3, R-1]

Explanation:

First – vacuum tubes; Second – transistors; Third – integrated circuits.

2.  
Chronological orderArrange in chronological order:
1. Turing machine paper
2. Napier's bones
3. Hollerith's census tabulator
4. Transistor

Correct Answer: D [2, 3, 1, 4]

Explanation:

Napier's bones (1617) → Hollerith's census tabulator (1890) → Turing machine paper (1936) → Transistor (1947)

3.  
Odd one outOdd one out (by generation):

Correct Answer: B [IBM PC]

Explanation:

ENIAC, EDVAC and UNIVAC I are first-generation (vacuum tubes); the IBM PC (1981) is fourth-generation.

4.  
Assertion–Reason
A: Second-generation computers produced much less heat than first-generation computers.
R: Transistors are smaller and need far less power than vacuum tubes.

Correct Answer: A [Both A and R are true and R explains A]

Explanation:

Both true; less power and size of transistors is exactly why heat fell.

5.  
Who published notes (1843) containing an algorithm meant for Babbage's Analytical Engine?

Correct Answer: B [Ada Lovelace]

Explanation:

Ada Lovelace's notes (1843) – she is often called the first programmer.

6.  
Joseph Marie Jacquard's loom of the early 1800s is remembered in computing history because its patterns were controlled by:

Correct Answer: A [punched cards]

Explanation:

Jacquard's loom read punched cards – the idea later used by Babbage and Hollerith.

7.  
First-generation computers were programmed mainly in:

Correct Answer: D [Machine language]

Explanation:

Generation 1 used machine language (0s and 1s); COBOL came with generation 2.

8.  
Fill in the blankThe ability of a computer to work for long hours without tiredness or loss of concentration is called ______.

Correct Answer: C [diligence]

Explanation:

Diligence = no fatigue; versatility = many kinds of work.

9.  
True/False countHow many of these statements are true?
(i) A mainframe can serve many users at the same time.
(ii) A microcomputer is built around a microprocessor.
(iii) An analog computer works with discrete digits 0 and 1.
(iv) Supercomputers are used for weather forecasting.

Correct Answer: D [3]

Explanation:

(i), (ii), (iv) are true; (iii) is false – analog works with continuous quantities, digital with 0/1.

10.  
Babbage's Analytical Engine had a 'mill' and a 'store'. In a modern computer these correspond to:

Correct Answer: C [ALU and memory]

Explanation:

Mill = where arithmetic is done (ALU); store = where numbers are kept (memory).

11.  
The stored-program concept, in which program and data share the same memory, is linked with:

Correct Answer: A [John von Neumann]

Explanation:

Von Neumann's 1945 report on EDVAC described the stored-program design.

12.  
Fifth-generation computers are mainly associated with:

Correct Answer: D [Artificial intelligence]

Explanation:

Fifth generation: AI, ULSI, parallel processing, natural language.

13.  
Which of the following is a second-generation computer?

Correct Answer: B [IBM 1401]

Explanation:

IBM 1401 used transistors (gen 2); ENIAC/UNIVAC I – gen 1; IBM PC – gen 4.

14.  
Reverse questionThe answer is 'microprocessor'. Which question fits?

Correct Answer: A [Which device marks the start of the fourth generation?]

Explanation:

Microprocessor → fourth generation.
