The third generation of computers saw the emergence and popularization of online real-time systems.
Q29.Super Computer invented by ______?
Correct Answer: C
Supercomputers were pioneered in the 1960s, and the fastest were designed by Seymour Cray, who is considered the father of supercomputing.
Q30.Microprocessors was introduced in which generation of computer?
Correct Answer: B
Microprocessors (VLSI technology) were introduced during the Fourth Generation of computers, starting in the early 1970s.
Q31.IBM 1401 is_____?
Correct Answer: D
The IBM 1401 is an iconic second-generation computer which relied on transistor-based technology.
Q32.Which of the following technologies was used in second generation computer?
Correct Answer: B
Second-generation computers (1956–1963) replaced hot, bulky vacuum tubes with solid-state transistors.
Q33.Humanoid robot is an example of which computer generation?
Correct Answer: B
Fifth-generation computing represents advanced research into AI, natural language processing, parallel processing systems, and robotics (such as humanoid robots).
Q34.What was the reason for the availability of low-cost computers during the third generation of computers?
Correct Answer: B
The development of Integrated Circuits (ICs) allowed engineers to fit hundreds of transistors onto a single silicon chip, drastically reducing computer size, power consumption, and production costs during the third generation (1964-1971).
Q35.Who invented Integrated Circuit (IC)?
Correct Answer: A
Jack Kilby of Texas Instruments (along with Robert Noyce of Fairchild Semiconductor) invented the first integrated circuit chip in 1958.
Q36.The third generation computers could carry out instructions in ______ of a second.
Correct Answer: B
Third generation computers (1960s–70s) used integrated circuits (ICs), enabling them to execute instructions in millionths of a second (microseconds).
Q37.Which distributed computing model processes and analyzes data directly at or near the source of generation instead of a centralized cloud server?
Correct Answer: A
Edge computing places processing, analysis, and storage resources near the physical location of the data source, lowering latency and bandwidth use.
Q38.Which historical figure is widely regarded as the primary pioneer who conceptualized and developed the design for the modern programmable computer?
Correct Answer: C
Charles Babbage conceptualized and designed the first mechanical programmable computer (the Analytical Engine) in the 1830s.
Q39.Who invented the the first Digital Computer?
Correct Answer: A
John Vincent Atanasoff invented the Atanasoff-Berry Computer (ABC), recognized as the first digital electronic computer (1930s-1942).
Q40.Who is historically credited with developing the first-ever software compiler (the A-0 compiler) in 1952?
Correct Answer: B
Rear Admiral Grace Hopper invented the first software compiler in 1952, paving the way for high-level languages.
