Q41. Which of the following computers was the first stored-program computer?
a) ENIAC
b) EDVAC
c) EDSAC
d) UNIVAC I
Show Answer
Correct Answer: c) EDSAC
Explanation: EDSAC (Electronic Delay Storage Automatic Calculator) was the first stored-program computer, developed at the University of Cambridge in 1949. It used mercury delay lines for memory and could execute a stored program, making it a significant milestone in the development of modern computers.
Q42. Which of the following computers was the first commercially available computer?
a) ENIAC
b) EDVAC
c) EDSAC
d) UNIVAC I
Show Answer
Correct Answer: d) UNIVAC I
Explanation: UNIVAC I (UNIVersal Automatic Computer I) was the first commercially available computer, developed by J. Presper Eckert and John Mauchly in 1951. It was used for a variety of applications, including scientific research, military calculations, and business data processing.
Q43. Which of the following is a key feature of the first 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: a) Use of vacuum tubes
Explanation: The first generation of computers used vacuum tubes as their primary electronic component. These tubes were large, consumed a lot of power, and generated significant heat, making the computers of this era bulky and inefficient compared to later generations.
Q44. What was the primary disadvantage of using vacuum tubes in the first generation of computers?
a) Low processing speed
b) High power consumption
c) Limited storage capacity
d) Lack of artificial intelligence capabilities
Show Answer
Correct Answer: b) High power consumption
Explanation: The use of vacuum tubes in the first generation of computers led to high power consumption, which made the computers of this era inefficient and prone to failure due to overheating. This issue was addressed in later generations with the introduction of transistors and integrated circuits.
Q45. Which generation of computers is most closely associated with the development of the internet?
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 is most closely associated with the development of the internet. The increased processing power and miniaturization provided by microprocessors allowed for the creation of advanced networking technologies, which ultimately led to the widespread adoption of the internet.
Q46. What is the primary focus of the fourth generation of computers?
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.
Q47. 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.
Q48. What was the main programming language used in the first generation of computers?
a) Assembly language
b) Machine language
c) COBOL
d) FORTRAN
Show Answer
Correct Answer: b) Machine language
Explanation: The first generation of computers used machine language as the programming language. Machine language is a low-level programming language consisting of binary code, which is difficult for humans to read and write.
Q49. Which of the following is NOT a characteristic of the second generation of computers?
a) Use of transistors
b) Smaller size compared to the first generation
c) Use of vacuum tubes
d) Faster than the first generation
Show Answer
Correct Answer: c) Use of vacuum tubes
Explanation: The second generation of computers used transistors instead of vacuum tubes, making them smaller, more reliable, and faster than the first generation. They were used from 1957 to 1963.
Q50. Which of the following computers is an example of a first-generation computer?
a) IBM 370
b) IBM 7094
c) ENIAC
d) PDP-11
Show Answer
Correct Answer: c) ENIAC
Explanation: ENIAC (Electronic Numerical Integrator and Computer) was a first-generation computer that used vacuum tubes for logic circuitry. It was one of the earliest electronic general-purpose computers.
