1)What kind of logic device or circuit is used to store information? Counter Register Inverter Buffer **Answer:** Option B 2) Which statement below best describes a Karnaugh map? A Karnaugh map can be used to replace Boolean rules. The Karnaugh map eliminates the need for using NAND and NOR gates. Variable complements can be eliminated by using Karnaugh maps. Karnaugh maps provide a visual approach to simplifying Boolean expressions. **Answer:** Option D 3) The device shown here is most likely a \_\_\_\_\_\_\_\_. comparator multiplexer demultiplexer parity generator **Answer:** Option C 4) How many 2-input NOR gates does it take to produce a 2-input NAND gate? 1 2 3 4 **Answer:** Option D 5) A decoder can be used as a demultiplexer by \_\_\_\_\_\_\_\_. tying all enable pins LOW tying all data-select lines LOW tying all data-select lines HIGH using the input lines for data selection and an enable line for data input **Answer:** Option D 1)Who is the founder of the modern theory of evolution?\ \ Charles Darwin\ Isaac Newton\ Albert Einstein\ Marie Curie\ Correct Answer: a\ \ 2)Which country is considered the birthplace of the Olympic Games?\ \ Greece\ Rome\ Egypt\ China\ Correct Answer: a\ \ 3) What event led to the start of World War II?\ \ The fall of the Berlin Wall\ Attack on Pearl Harbor\ The signing of the Treaty of Versailles\ The capture of Crimea by Germany\ Correct Answer: b\ \ 4) In which country did the Chernobyl nuclear disaster take place?\ \ Russia\ Ukraine\ Belarus\ Lithuania\ Correct Answer: b\ \ 5) What is the phobia of thunder and rain?\ \ Agoraphobia\ Ombrophobia\ Acrophobia\ Claustrophobia\ Correct Answer: b\ \ 6) Galvanized steel are steel product coated with\ \ A.Zinc\ B.Iron\ C.Silicon\ D.Boron\ Correct Answer\ A.

Lumen/watt\ \ 10) How many dynes in one newton?\ \ A.10,000\ B.100,000\ C.1,000,000\ D.1,000\ Correct Answer\ B. 100,000\ \ 11) Q1 What is an object in object-oriented programming?\ A\ A code snippet\ B\ A variable\ C\ An instance of a class\ D\ A function\ \ Option c\ \ 12) In OOP, what does encapsulation refer to?\ A\ Storing data in arrays\ B\ The process of inheritance\ C\ Combining data and methods\ D\ A type of loop\ \ Option c\ \ 13) Q1 What is the primary goal of Artificial Intelligence?\ A\ To create systems that require human input to operate\ B\ To develop systems that simulate human intelligence processes\ C\ To replace all jobs currently performed by humans\ D\ To enhance computer processing speeds\ \ Option b\ \ 14) In Python, which algorithm would you use to solve a maze problem?\ A\ Depth-first search\ B\ Binary search\ C\ Linear search\ D\ Bubble sort\ \ Option a\ \ 15) Which company developed Android?\ A\ Microsoft\ B\ Apple\ C\ Google\ D\ Facebook\ \ Option c 1)At room temperature the current in an intrinsic semiconductor is due to holes electrons ions holes and electrons **Answer:** Option  D **Explanation:** Intrinsic material has equal number of holes and electrons.  2)  In which of these is reverse recovery time nearly zero? Zener diode Tunnel diode Schottky diode PIN diode **Answer:** Option  C **Explanation:** In schottky diode there is no charge storage and hence almost zero reverse recovery time. 3) A transistor has a current gain of 0.99 in the CB mode. Its current gain in the CC mode is 100 99 1.01 0.99 **Answer:** Option  A **Explanation:**  Current gain = 1 + β = 100. 4) In a bipolar transistor which current is largest collector current base current emitter current base current or emitter current **Answer:** Option  C **Explanation:** Emitter current is larger, collector current is slightly less than emitter current and base current is very small. 5) The normal operation of JFET is constant voltage region constant current region both constant voltage and constant current regions either constant voltage or constant current region **Answer:** Option B **Explanation:** In major portion of drain characteristics ID is constant. 1)GRAVITY:PULL iron:metal north pole:directions magnetism:attraction dust:desert **Answer:** Option C 2) The calendar for the year 2007 will be the same for the year: 2014 2016 2017 2018 Option D Count the number of odd days from the year 2007 onwards to get the sum equal to 0 odd day. Year : 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 Odd day : 1 2 1 1 1 2 1 1 1 2 1  Sum = 14 odd days   0 odd days.  Calendar for the year 2018 will be the same as for the year 2007. 3) Find a positive number which when increased by 17 is equal to 60 times the reciprocal of the number. 3 10 17 20 **Your Answer:** Option  (Not Answered) **Correct Answer:** Option  A **Explanation:** Let the number be *x*. Then, *x* + 17 = 60 ------------------ ----- *x*  *x*2 + 17*x* - 60 = 0  (*x* + 20)(*x* - 3) = 0  *x* = 3. 4) The sum of two number is 25 and their difference is 13. Find their product. 104 114 315 325 **Your Answer:** Option  (Not Answered) **Correct Answer:** Option  **Explanation:** Let the numbers be *x* and *y*. Then, *x* + *y* = 25 and *x* - *y* = 13. 4*xy* = (*x* + *y*)2 - (*x*- *y*)2    = (25)2 - (13)2    = (625 - 169)    = 456  *xy* = 114. 5)Find out the wrong number in the given sequence of numbers. 6, 13, 18, 25, 30, 37, 40 25 30 37 40  The differences between two successive terms from the beginning are 7, 5, 7, 5, 7, 5. So, 40 is wrong.
