Statics MCQs for UPSC & State PSC Exams

Q1:

Consider the following statements about the development of computers:

1. Charles Babbage is often considered the "Father of the Computer."

2. The first electronic computer was ENIAC, which was developed during World War II.

3. Alan Turing is known for his contribution to the development of modern computers.

How many of the above statements are correct?

A: Only one

B: Only two

C: All three

D: None

Show

Answer: (c)

Explanation:

Charles Babbage is often considered the "Father of the Computer" for his pioneering work on mechanical computing engines.

ENIAC, developed during World War II, was the first electronic digital computer of significant size and complexity.

Alan Turing made significant contributions to code-breaking and laid the foundation of modern computers.

Hence all the statements are correct.

Q2:

With reference to the development of telecommunication, consider the following pairs:

1. Guglielmo Marconi: Radio

2. Alexander Graham Bell: Telephone

3. Robert Morse: Telegraph

How many of the above pairs are correctly matched?

A: Only one pair

B: Only two pairs

C: All three pairs

D: No pair

Show

Answer: (c)

Explanation:

Guglielmo Marconi made important advances in radio technology and conducted the first transatlantic radio transmission.

Alexander Graham Bell invented the telephone, revolutionizing communications.

Robert Morse developed Morse code, a system of dots and dashes for transmitting messages via telegraph.

Hence all the pairs are correctly matched.

Q3:

Consider the following statements about computer languages:

Statement-I: HTML is a programming language used for web development.

Statement-II: Python is a high level programming language.

Which of the following is correct regarding the above statements?

A: Both Statement-I and Statement-II are correct and Statement-II is the correct explanation of Statement-I.

B: Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation of Statement-I.

C: Statement-I is correct but Statement-II is wrong

D: Statement-I is wrong but Statement-II is correct

Show

Answer: (d)

Explanation:

HTML is a markup language used to structure and present content on web pages, not a programming language in the traditional sense.

Python is a high-level, general-purpose programming language known for its readability, versatility, and wide range of applications.

Hence Statement-I is not correct but Statement-II is correct.

Q4:

Consider the following statements about supercomputers:

1. Supercomputers are designed for highly complex calculations.

2. Cray-1 was one of the earliest supercomputers.

3. Supercomputers are commonly used for scientific simulations.

How many of the above statements are correct?

A: Only one

B: Only two

C: All three

D: None

Show

Answer: (c)

Explanation:

Supercomputers are actually designed to deal with extremely complex calculations that require immense processing power.

The Cray-1, developed in 1976, was one of the first commercially successful supercomputers, paving the way for later advances.

Scientific simulations are a common application of supercomputers, as they are used to model complex phenomena in fields such as physics, chemistry, and climate research.

Hence all three statements are correct.

Q5:

Which of the following statements is/are correct regarding the development of telecommunication?

A: The first telegraph lines were used for long distance communication in the 19th century.

B: The invention of the telephone in the 19th century revolutionized communication, making it more personal and immediate.

C: Mobile phones, first introduced in the 1980s, have become increasingly sophisticated and ubiquitous.

D: All of the above

Show

Answer: (d)

Explanation:

The first telegraph lines were installed in the 1830s, enabling long-distance communication compared to earlier methods.

The telephone, invented in 1876, revolutionized communication by allowing voice conversations in real time over distance, making it more personal and immediate.

First commercially introduced in the 1980s, mobile phones have evolved rapidly, becoming increasingly sophisticated and ubiquitous in modern society.

Hence option (d) is correct.
