Q51. What was the main programming language used in the third generation of computers?
a) Assembly language
b) Machine language
c) COBOL
d) FORTRAN
Show Answer
Correct Answer: c) COBOL
Explanation: The third generation of computers used high-level programming languages like COBOL (Common Business-Oriented Language) and FORTRAN (Formula Translation). These languages made programming more efficient and easier to understand compared to assembly language used in the second generation.
Q52. Which of the following computers is an example of a second-generation computer?
a) IBM 1920
b) IBM 701
c) IBM System/360
d) UNIVAC 1108
Show Answer
Correct Answer: a) IBM 1920
Explanation: The IBM 1920 was a second-generation computer that used transistors instead of vacuum tubes. Some other examples of second-generation computers include IBM 7094, CDC 1604, CDC 3600, and IBM 1401.
Q53. Which of the following is a characteristic of the third generation of computers?
a) Use of vacuum tubes
b) Use of transistors
c) Use of integrated circuits
d) Use of microprocessors
Show Answer
Correct Answer: c) Use of integrated circuits
Explanation: The third generation of computers used integrated circuits (ICs) instead of transistors. ICs are semiconductor materials that contain thousands of miniaturized transistors, making these computers more reliable, smaller, and faster than the previous generations.
Q54. What was the main programming language used in the second generation of computers?
a) Assembly language
b) Machine language
c) COBOL
d) FORTRAN
Show Answer
Correct Answer: a) Assembly language
Explanation: The second generation of computers used assembly language, which is a low-level programming language that uses mnemonic codes to represent machine language instructions. This made programming easier and more efficient compared to machine language used in the first generation.
Q55. What was the main advantage of using microprocessors in the fourth generation of computers?
a) Increased storage capacity
b) Improved reliability and reduced size
c) Introduction of high-level programming languages
d) Development of personal computers
Show Answer
Correct Answer: d) Development of personal computers
Explanation: The use of microprocessors in the fourth generation of computers led to the development of personal computers, making computing more accessible and affordable for individuals and small businesses.
