Q21. Who was one of the conceptual inventors of the stored-program digital computer, along with Alan Turing and Claude Shannon?
a) Blaise Pascal
b) Charles Babbage
c) Gottfried Wilhelm von Leibniz
d) John von Neumann
Show Answer
Correct Answer: d) John von Neumann
Explanation: John von Neumann, along with Alan Turing and Claude Shannon, was one of the conceptual inventors of the stored-program digital computer. Von Neumann grew from a child prodigy to one of the world’s foremost mathematicians and made important contributions to various branches of mathematics. His work in applied mathematics influenced quantum theory, automata theory, economics, and defense planning.
Q22. Which generation of computers is most closely associated with the development of graphical user interfaces (GUIs)?
a) First Generation
b) Second Generation
c) Third Generation
d) Fourth Generation
Show Answer
Correct Answer: d) Fourth Generation
Explanation: The fourth generation of computers saw the development of graphical user interfaces (GUIs), which made computers more user-friendly and accessible to a wider audience. This innovation contributed to the widespread adoption of personal computers.
Q23. Which of the following is NOT a characteristic of the fifth generation of computers?
a) Advanced artificial intelligence capabilities
b) Parallel processing
c) Use of vacuum tubes
d) Natural language processing
Show Answer
Correct Answer: c) Use of vacuum tubes
Explanation: The fifth generation of computers focuses on advanced computing techniques, such as artificial intelligence, parallel processing, and natural language processing. Vacuum tubes, which were used in the first generation of computers, are not a characteristic of the fifth generation.
Q24. Who invented the Stepped Reckoner, a calculating machine that could add, subtract, multiply, and divide?
a) Blaise Pascal
b) Charles Babbage
c) Gottfried Wilhelm von Leibniz
d) John von Neumann
Show Answer
Correct Answer: c) Gottfried Wilhelm von Leibniz
Explanation: Gottfried Wilhelm von Leibniz invented the Stepped Reckoner, a calculating machine that could add, subtract, multiply, and divide. The Stepped Reckoner used a series of gears and pins to perform calculations and was an improvement on Pascal’s Pascaline, which could only perform addition and subtraction.
Q25. What was the main advantage of using integrated circuits in the third generation of computers?
a) Increased storage capacity
b) Improved reliability and reduced size
c) Introduction of high-level programming languages
d) Use of parallel processing
Show Answer
Correct Answer: b) Improved reliability and reduced size
Explanation: The use of integrated circuits in the third generation of computers led to improved reliability, reduced size, and lower power consumption compared to the second generation that used transistors.
Q26. Which of the following computers is an example of a third-generation computer?
a) IBM 370
b) IBM 7094
c) ENIAC
d) PDP-11
Show Answer
Correct Answer: a) IBM 370
Explanation: The IBM System/360, also known as IBM 370, was a third-generation computer that used integrated circuits. It was a family of mainframe computers that introduced the concept of a compatible computer architecture.
Q27. What was the primary storage medium used in the first generation of computers?
a) Magnetic tape
b) Hard disk drives
c) Solid-state drives
d) Cloud storage
Show Answer
Correct Answer: a) Magnetic tape
Explanation: The first generation of computers primarily used magnetic tape as a storage medium. Magnetic tape was a sequential access storage device, which made data retrieval slower compared to later storage technologies.
Q28. Which of the following is a characteristic of second-generation computers?
a) Use of vacuum tubes
b) Development of high-level programming languages
c) Use of integrated circuits
d) Use of microprocessors
Show Answer
Correct Answer: b) Development of high-level programming languages
Explanation: The second generation of computers saw the development of high-level programming languages, such as COBOL and FORTRAN. These languages made it easier for programmers to write complex programs and increased the overall efficiency of software development.
Q29. What technology allowed for the development of smaller and more portable computers 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 smaller and more portable systems.
Q30. Which of the following is a key feature of the fifth generation of computers?
a) Use of vacuum tubes
b) Use of transistors
c) Use of integrated circuits
d) Advanced artificial intelligence capabilities
Show Answer
Correct Answer: d) Advanced artificial intelligence capabilities
Explanation: The fifth generation of computers focuses on advanced computing techniques, such as artificial intelligence, parallel processing, and natural language processing. These technologies aim to make computers more intelligent and capable of solving complex problems.
