a) IBM 1920
b) IBM 701
c) IBM System/360
d) Apple II
Show Answer
Correct Answer: d) Apple II
Explanation: The Apple II, introduced in 1977, was a fourth-generation computer that used a microprocessor. It was one of the first successful personal computers and played a significant role in popularizing home computing.
Q33. Which generation of computers introduced the concept of time-sharing?
a) First Generation
b) Second Generation
c) Third Generation
d) Fourth Generation
Show Answer
Correct Answer: c) Third Generation
Explanation: The third generation of computers introduced the concept of time-sharing, which allowed multiple users to access a computer system simultaneously. This innovation improved the overall efficiency of computer systems and made them more accessible to a larger number of users.
Q34. What is the primary advantage of using microprocessors in the fourth generation of computers?
a) Increased processing speed
b) Reduced size and power consumption
c) Improved artificial intelligence capabilities
d) Introduction of personal computers
Show Answer
Correct Answer: a) Increased processing speed
Explanation: The use of microprocessors in the fourth generation of computers led to significant increases in processing speed compared to integrated circuits. This allowed for more powerful and efficient computer systems, paving the way for the development of personal computers and other advanced devices.
Q35. Which of the following is NOT a characteristic of the third generation of computers?
a) Use of integrated circuits
b) Smaller size compared to the second generation
c) Use of vacuum tubes
d) Faster than the second generation
Show Answer
Correct Answer: c) Use of vacuum tubes
Explanation: The third generation of computers used integrated circuits instead of vacuum tubes, making them more reliable, smaller, and faster than the previous generations.
Q36. Which of the following is an example of a fifth-generation computer?
a) IBM 370
b) IBM 7094
c) ENIAC
d) IBM Watson
Show Answer
Correct Answer: d) IBM Watson
Explanation: IBM Watson is an example of a fifth-generation computer that uses artificial intelligence and advanced parallel processing techniques. Watson is capable of understanding natural language, recognizing patterns, and learning from experience.
Q37. Which of the following computers was the first general-purpose electronic computer?
a) ENIAC
b) EDVAC
c) EDSAC
d) UNIVAC I
Show Answer
Correct Answer: a) ENIAC
Explanation: ENIAC (Electronic Numerical Integrator and Computer) was the first general-purpose electronic computer, developed by J. Presper Eckert and John Mauchly in 1946. It used vacuum tubes for logic circuitry and was one of the earliest electronic general-purpose computers.
Q38. Which of the following is a key feature of the second 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: b) Use of transistors
Explanation: The second generation of computers replaced vacuum tubes with transistors, which were smaller, more reliable, and consumed less power. This led to significant improvements in computer performance and efficiency.
Q39. What was the main advantage of using high-level programming languages in the third and fourth generations of computers?
a) Increased storage capacity
b) Improved reliability and reduced size
c) Easier programming and improved efficiency
d) Development of personal computers
Show Answer
Correct Answer: c) Easier programming and improved efficiency
Explanation: The use of high-level programming languages in the third and fourth generations of computers made programming more efficient and easier to understand compared to assembly language used in the second generation.
Q40. What technology allowed for the development of more powerful and efficient computer systems during the third generation?
a) Vacuum tubes
b) Transistors
c) Integrated circuits
d) Microprocessors
Show Answer
Correct Answer: c) Integrated circuits
Explanation: The third generation of computers introduced the use of integrated circuits, which combined multiple transistors and other components onto a single silicon chip. This innovation further reduced the size and power consumption of computers, allowing for the development of more powerful and efficient computer systems.
