Question 1 of 7
A multiplexer is also known as - / एक मल्टीप्लेक्सर को इस रूप में भी जाना जाता है -
💡 Explanation: Multiplexer (MUX) me kai saari input lines hoti hain aur keval ek output line hoti hai. Yeh select lines ke aadhar par kisi ek input ko output par bhejta hai, isliye ise 'Data Selector' kehte hain.
Question 2 of 7
The 2's complement of the binary number (1101100)2 is - / बाइनरी संख्या (1101100)2 का 2's कम्प्लीमेंट है -
💡 Explanation: 1101100 ka 1's complement nikalne par 0010011 banta hai. Isme 1 jodte hi (+1) 2's complement '0010100' prapt hota hai.
Question 3 of 7
How many select lines are required for a 1-to-16 demultiplexer? / एक 1-से-16 डेमल्टीप्लेक्सर के लिए कितनी सेलेक्ट लाइनों की आवश्यकता होती है?
💡 Explanation: Demultiplexer me output lines (n) = 16 hain. Formula n = 2^m ke anusar, jahan m select lines hain, 16 = 2^4 hota hai. Isliye 4 select lines ki aavashyakta hogi.
Question 4 of 7
Which logic gate is known as the universal gate? / किस लॉजिक गेट को यूनिवर्सल गेट के रूप में जाना जाता है?
💡 Explanation: NAND aur NOR gates ko Universal Gates kaha jata hai kyunki inka upyog karke kisi bhi anya basic gate (AND, OR, NOT) ko banaya ja sakta hai.
Question 5 of 7
According to Boolean Algebra, the expression A + A'B is equal to - / बूलियन बीजगणित के अनुसार, व्यंजक A + A'B किसके बराबर है?
💡 Explanation: Distributive law ke anusar, A + A'B = (A + A')(A + B) hota hai. Chunki A + A' = 1 hota hai, isliye bacha hua parinaam hamesha 'A + B' hota hai.
Question 6 of 7
The hexadecimal representation of the binary number (10110111)2 is - / बाइनरी संख्या (10110111)2 का हेक्साडेसिमल निरूपण है -
💡 Explanation: Binary ko Hexadecimal me badalne ke liye 4-4 ke jode (groups) banate hain. 1011 ka matlab B (11) hota hai aur 0111 ka matlab 7 hota hai. Isliye sahi uttar 'B7' hai.
Question 7 of 7
A combinational circuit that converts n-line inputs to a maximum of 2^n distinct outputs is called - / एक कॉम्बिनेशनल सर्किट जो n-लाइन इनपुट को अधिकतम 2^n विशिष्ट आउटपुट में बदलता है, कहलाता है -
💡 Explanation: Decoder ek aisa combinational circuit hai jo n input lines ko lekar unhe maximum 2^n unique output lines me decode ya convert karta hai.
