Correct answer: C. Microprocessor basedमाइक्रोप्रोसेसर आधारित
Explanation
The microprocessor (e.g. Intel 4004 in 1971, followed by the 8080) put the whole CPU on one chip, making small, affordable personal computers possible in the 1970s – the fourth generation of computers. Vacuum tubes, transistors and ICs were the key technologies of the first, second and third generations. Answer: Microprocessor based.माइक्रोप्रोसेसर (जैसे 1971 का Intel 4004, फिर 8080) ने पूरे CPU को एक चिप पर रख दिया, जिससे 1970 के दशक में छोटे, सस्ते पर्सनल कंप्यूटर संभव हुए – यह कंप्यूटर की चौथी पीढ़ी है। निर्वात नलिका, ट्रांजिस्टर और IC क्रमशः पहली, दूसरी और तीसरी पीढ़ी की मुख्य प्रौद्योगिकियाँ थीं। उत्तर: माइक्रोप्रोसेसर आधारित।More Information and Communication Technology (ICT) questions
