Q11. What was the primary advantage of using transistors in the second 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: b) Reduced size and power consumption
Explanation: The use of transistors in the second generation of computers led to significant reductions in size and power consumption compared to vacuum tubes. This allowed for more efficient and reliable computer systems.
Q12. Which of the following is a key feature 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 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 more complex and powerful systems.
Q13. Which of the following computers was the first to use integrated circuits?
a) IBM 360
b) IBM 7094
c) IBM 1401
d) IBM 7090
Show Answer
Correct Answer: a) IBM 360
Explanation: The IBM System/360, also known as IBM 360, was the first computer to use integrated circuits. It was introduced in 1964 and marked the beginning of the third generation of computers.
Q14. What technology allowed the development of personal computers during the fourth generation?
a) Vacuum tubes
b) Transistors
c) Integrated circuits
d) Microprocessors
Show Answer
Correct Answer: d) Microprocessors
Explanation: The fourth generation of computers is characterized by the use of microprocessors, which integrated the entire central processing unit (CPU) onto a single chip. This allowed for even greater miniaturization and increased processing power, leading to the development of personal computers and other advanced devices.
Q15. Which of the following is a disadvantage of the first generation of computers?
a) Large size
b) High processing speed
c) Low power consumption
d) Advanced artificial intelligence capabilities
Show Answer
Correct Answer: a) Large size
Explanation: The first generation of computers used vacuum tubes, which were large and generated significant heat. This made the computers of this era bulky and inefficient compared to later generations.
Q16. Who is credited with refining the binary number system, which is the foundation of nearly all digital computers?
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 is credited with refining the binary number system, which is the foundation of nearly all digital computers. He documented the binary numeral system (base 2) early in his life and revisited it throughout his career. The binary number system uses symbols 0 and 1 for numbers and is the basis of modern digital computers, including the Von Neumann architecture.
Q17. Which generation of computers is associated with the development of high-level programming languages?
a) First Generation
b) Second Generation
c) Third Generation
d) Fourth Generation
Show Answer
Correct Answer: b) Second Generation
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.
Q18. What is the primary advantage of using integrated circuits in the third 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: b) Reduced size and power consumption
Explanation: The use of integrated circuits in the third generation of computers led to significant reductions in size and power consumption compared to transistors. This allowed for more efficient and powerful computer systems.
Q19. Which of the following computers was the first to use transistors?
a) IBM 701
b) IBM 650
c) IBM 1401
d) IBM 7090
Show Answer
Correct Answer: a) IBM 701
Explanation: The IBM 701 was the first computer to use transistors instead of vacuum tubes. It was introduced in 1952 and marked the beginning of the second generation of computers.
Q20. Which of the following is a key feature of the fourth 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: d) Use of microprocessors
Explanation: The fourth generation of computers is characterized by the use of microprocessors, which integrated the entire central processing unit (CPU) onto a single chip. This allowed for even greater miniaturization and increased processing power, leading to the development of personal computers and other advanced devices.
