In which generation did the 'Transistor' replace the 'Vacuum Tube'?
Correct Answer: B. Second Generation
Transistors were introduced in the second generation, starting around 1956. They performed the same function as vacuum tubes but were much smaller and cooler. This marks a major turning point in the history of electronics.
Which generation of computers made the first use of the 'Internet'?
Correct Answer: B. Fourth Generation
The fourth generation saw the growth of networking and the birth of the modern internet. Standard communication protocols were developed to allow different computers to talk to each other. This led to the global connectivity we have today.
Which generation is defined by the use of 'Expert Systems'?
Correct Answer: C. Fifth Generation
Fifth-generation computers use expert systems, which are AI programs that solve complex problems. They mimic the decision-making ability of a human expert in a specific field. This is a core application of modern AI technology.
Who is considered the 'Father of the Computer'?
Correct Answer: B. Charles Babbage
Charles Babbage designed the Analytical Engine, which is the conceptual basis for all modern computers. Although his machines were mechanical, they included features like an ALU and basic memory. His work paved the way for all future electronic computer generations.
The use of 'Magnetic Drums' for memory is a feature of which generation?
Correct Answer: A. First Generation
First-generation computers used magnetic drums as their primary internal memory storage. These were large metal cylinders that stored data magnetically on their outer surface. They were eventually replaced by more efficient magnetic cores.
Which generation of computers introduced the 'Microchip'?
Correct Answer: C. Third Generation
The microchip, or Integrated Circuit, was the invention that started the third generation. It allowed for the miniaturization of electronic circuits by placing them on a single chip. This transformed the computer from a niche tool into a common business machine.
Quantum computing and nanotechnology are part of which generation's research?
Correct Answer: B. Fifth Generation
Fifth-generation research includes cutting-edge fields like quantum computing and nanotechnology. These technologies aim to process data at atomic scales and speeds. They represent the next major leap beyond traditional silicon-based computers.
Which generation of computers used 'Punch Cards' for input?
Correct Answer: A. First Generation
First-generation computers used punch cards and paper tape for both input and output. Data was represented by holes punched into stiff paper cards. This remained a common method of input for several decades before keyboards became standard.
Which generation of computers introduced Artificial Intelligence (AI) and parallel processing as key features?
Correct Answer: C. Fifth Generation
Fifth-generation computers (1980s-present) are characterized by the use of Artificial Intelligence (AI), parallel processing, and ultra-large-scale integration (ULSI). These computers are designed to respond to natural language input and are capable of learning and self-organization.
The second generation of computers used transistors instead of vacuum tubes. What was the primary advantage of transistors?
Correct Answer: B. They generated less heat and were more reliable
Transistors, used in second-generation computers (1956-1963), generated significantly less heat compared to vacuum tubes, were more reliable, smaller in size, faster, cheaper, and consumed less energy. This made second-gen computers more efficient and commercially viable than first-gen machines.
