Computers · पीढ़ियां · Questions 31–40 of 70
Magnetic cores were used for primary memory in which generation?
Correct Answer: B. Second
Second-generation computers used magnetic cores for internal storage. These tiny doughnut-shaped rings could store a bit of data each. This was much faster and more reliable than the magnetic drums of the first generation.
Which generation of computers introduced the use of the Mouse as an input device?
Correct Answer: D. Fourth
Fourth-generation computers saw the introduction and mass adoption of the mouse. It was essential for navigating the newly developed Graphical User Interfaces. This made computing intuitive and accessible for non-technical users.
Multi-programming was a major software advancement in which generation?
Correct Answer: D. Third
Third-generation computers used operating systems that supported multi-programming. This allowed the CPU to switch between different tasks to maximize efficiency. It paved the way for the complex multitasking we see in modern devices.
What was the main physical characteristic of first-generation computers?
Correct Answer: B. Enormous room-sized
First-generation computers were massive because of the thousands of vacuum tubes required. They were heavy, immobile, and required a lot of space. For example, the ENIAC weighed about 30 tons.
High-level languages like PASCAL and BASIC became popular in which generation?
Correct Answer: C. Third
Third-generation computing saw the rise of many user-friendly high-level languages. BASIC and PASCAL made it easier for students and hobbyists to learn programming. This contributed to the widespread use of computers in educational institutions.
Which generation used 'Magnetic Drums' for primary storage?
Correct Answer: A. First
Magnetic drums were the primary memory source for many first-generation machines. They spun at high speeds to allow read/write heads to access data. This was the precursor to modern hard disk technology.
Bio-chips and Gallium Arsenide (GaAs) technology are related to which generation?
Correct Answer: C. Fifth
Fifth-generation research involves using advanced materials like GaAs for faster circuits. Scientists are also exploring the use of biological components in 'Bio-chips'. These technologies aim to overcome the physical limits of traditional silicon chips.
Which era saw the invention of the World Wide Web (WWW)?
Correct Answer: C. Fourth Generation
The World Wide Web was developed during the fourth generation of computers. Tim Berners-Lee created the first web browser and server while at CERN. This revolutionized how information is shared globally across computer networks.
The use of 'Very Large Scale Integration' (VLSI) chips is the core of which generation?
Correct Answer: C. Fourth
Fourth-generation computers are defined by VLSI technology. It allowed for millions of transistors to be placed on a single microprocessor. This led to a massive increase in computing power per square inch.
Which generation is considered to be in the 'Experimental' or 'Future' phase regarding AI?
Correct Answer: D. Fifth
Fifth-generation computers are currently evolving and focus on complex AI. While many AI features exist, the goal of true machine intelligence is still being researched. This generation represents the cutting edge of modern computer science.
