I TERM EXAMINATION 2023-24 CLASS: XII SUBJECT: COMPUTER SCIENCE PAPER 1 (THEORY) (Maximum Marks: 70) (Time allowed: Three hours) (Candidates are allowed additional 15 minutes for only reading the paper. They must NOT start writing during this time.)Answer all questions in Part I (compulsory) and six questions from Part II,choosing two questions from Section-A, two from Section B and two from Section C.All working, including rough work, should be done on the same sheet as the rest of the answer.The intended marks for questions or parts of questions are given in brackets [ ]. PART - I(20 Marks) Answer all questions. While answering questions in this Part, indicate briefly your working and reasoning, wherever required. QUESTION 1: [10x1=10] i) Distributive law states that: a) A ( A + B) = A b) A + ( A B) = A c) Both (a) and (b) d) A ( B + C ) = A B + A C ii) Assertion STATEMENT 1: (p q)is equivalent to (p q) ( p q) Reason STATEMENT 2: (p q) is equivalent to (p q) ( p q) a) Statement 1 is True, Statement 2 is True; Statement 2 is a correct explanation for Statement 1 b) Statement 1 is True, Statement 2 is True; Statement 2 is NOT a correct explanation for Statement 1 c) Statement 1 is True, Statement 2 is False d) Statement 1 is False, Statement 2 is True iii) Find the dual expression for Y= ABC+A BC+ABC a) (A+B+C)(A +B+C)(A+B+C ) b) (A +B +C )(A+B +C )(A +B +C) c) AB+A B+AB d) None of the above iv) Simplification of the Boolean expression AB + ABC + ABCD + ABCDE + ABCDEF yields which of the following results? a) ABCDEF b) AB c) AB + CD + EF d) A + B + C + D + E + F v) Given that F = (A + B'+ C)(D + E), which of the following represents the only correct expression for F'? a) F' = A'BC'+ D'+ E' b) F' = AB'C + DE c) F' = (A'+ B + C')(D'+ E') d) F' = A'BC' + D'E' vi) Assertion : In an OR gate if any of the input is high, the output is high. Reason: OR gate is the most basic gate, with one input and one output a) If both assertion and reason are true and reason is the correct explanation of assertion. b) If both assertion and reason are true not but reason is not the correct explanation of assertion. c) If assertion is true but reason is false d) If both assertion and reason are false. vii) Implicit type conversion in java is also called________. a) Narrowing type conversion b) Widening type conversion c) No type conversion d) None of the above viii) Difference between Encapsulation and abstraction is : a) Binding and Hiding respectively=== b) Hiding and Binding respectively c) Can be used any way d) Hiding and hiding respectively ix) Which of the following is higher data type in Java language? a) Data type which holds more data than other data types b) Order type whose size is more than other data type c) Order type which can hold more precision digits than other data type d) All of the above x) The memory location where the object is stored is known as? QUESTION 2: [10] i) Write Cardinal form for the given expression f(a,b,c) = a b c + abc + ab c + a bc ii) An array ARR[ 4 ..6, 2 ..12] stores elements in Row Major Wise, with the address ARR[2][3] as 4142. If each element requires 2 bytes of storage, find the Base address. iii) The following function is a part of some class. It sorts the array a[ ] in ascending order using insertion sort technique. There are some places in the code marked by ?1?, ?2?, ?3?, ?4?, ?5? which must be replaced by expression / statement so that the function works correctly. void insertsort (int a [ ]) {
