Second Generation computers can be characterized largely by their use of:
Correct Answerसही उत्तर
D. TransistorsD. ट्रांजिस्टर
Explanationव्याख्या
The correct answer is Transistors.
According to the source, generations of computers are characterised by the technology they use.
The book states that first-generation digital computers, developed mostly in the United States after World War II, used vacuum tubes and were enormous in size.
It then says that the second generation, introduced in 1960, used transistors and consisted of the first successful commercial computers.
Therefore the central source-supported comparison is: First Generation — Vacuum Tubes — very large computers; Second Generation — introduced in 1960 according to the source — Transistors — first successful commercial computers.
Integrated Circuits, Vacuum Tubes and Microprocessors are distractors for the second-generation question.
The question is valuable because computer-generation questions are often asked through technology matching.
Students should avoid remembering only the word 'transistor' and instead connect it with the broader generational sequence supplied by the book.
The source does not explain third- or fourth-generation technologies in this particular entry, even though Integrated Circuits and Microprocessors appear as options.
Therefore those options have not been expanded into a complete generation table using outside knowledge.
Likewise, no exact computer models are listed.
Quick revision based on the source: First Generation = Vacuum Tubes; Second Generation = Transistors; source says Second Generation introduced in 1960 and included the first successful commercial computers.
Therefore option (d), Transistors, is correct.
सही उत्तर Transistors है। स्रोत के अनुसार computer generations को मुख्य रूप से उनकी technology के आधार पर characterize किया जाता है। Book बताती है कि First Generation digital computers, जो mostly World War II के बाद United States में developed हुए, vacuum tubes use करते थे और बहुत बड़े थे। इसके बाद source कहती है कि Second Generation को 1960 में introduce किया गया, इसमें transistors use हुए और ये first successful commercial computers थे। इसलिए main source-supported comparison है: First Generation — Vacuum Tubes — Enormous Computers; Second Generation — Source के अनुसार Introduced in 1960 — Transistors — First Successful Commercial Computers। Integrated Circuits, Vacuum Tubes और Microprocessors second-generation question में distractors हैं। Computer-generation questions frequently technology matching पर आधारित होते हैं, इसलिए केवल 'Transistor' word याद करने के बजाय source का comparative sequence याद करना useful है। Book इस entry में Third या Fourth Generation की technologies explain नहीं करती, भले ही Integrated Circuits और Microprocessors options में दिए गए हैं। इसलिए outside knowledge से full generation table नहीं जोड़ा गया है। Exact computer models भी source नहीं देती। Quick revision: First Generation = Vacuum Tubes; Second Generation = Transistors; Source: Second Generation introduced in 1960 and first successful commercial computers। इसलिए विकल्प (d), Transistors, सही उत्तर है।
