GATE EXAM - 2011 PATTERN

QUESTION PAPER PATTERN

The question paper will consist of only objective type questions. Candidates have to mark the correct choice by darkening the appropriate bubble against each question on an Objective Response Sheet (ORS). There will be negative marking for wrong answers. The deduction for each wrong answer will be 25% of the allotted marks.

Each paper contains 60 questions carrying 100 marks.

Types of multiple choice questions

Multiple choice questions in all papers and sections will contain four answers, of which only one is correct. The types of questions in a paper may be based on following logic:

(i) Recall:
These are based on facts, principles, formulae or laws of the discipline. The candidate is expected to be able to obtain the answer either from his/her memory of the subject or at most from a one-line computation.

Example
Q. During machining maximum heat is produced
(A) in flank face (B) in rake face
(C) in shear zone (D) due to friction between chip and tool.

(ii) Comprehension:
These questions will test the candidate?s understanding of the basics of his/her field, by requiring him/her to draw simple conclusions from fundamental ideas.

Example
Q. A DC motor requires a starter in order
(A) to develop a starting torque
(B) to compensate for auxiliary field ampere turns
(C) to limit armature current at starting
(D) to provide regenerative braking

(iii) Application: In these questions, the candidate is expected to apply his/her knowledge either through computation or by logical reasoning.

Example
Q. The sequent depth ratio of a hydraulic jump in a rectangular channel is 16.48. The Froude number at the beginning of the jump is:
(A) 10.0 (B) 5.0
(C) 12.0 (D) 8.0

(iv) Analysis and Synthesis:
These can be linked questions, where the answer to the first question of the pair is required in order to answer its successor. Or these can be common data questions, in which two questions share the same data but can be solved independently of one another.

Common data questions:
Multiple questions may be linked to a common data problem, passage and the like. Two or three questions can be formed from the given common data problem. Each question is independent and its solution obtainable from the above problem data/passage directly. (Answer of the previous question is not required to solve the next question). Each question under this group will carry two marks.

Example
Common Data, for instance, Questions 55 and 56 in main paper:
Let X and Y be jointly distributed random variables such that the conditional distribution of Y, given X=x, is uniform on the interval (x-1,x+1). Suppose E(X)=1 and Var(X)=5/3.

First question using common data:
Q.55 The mean of the random variable Y is
(A) 1/2 (B) 1 (C) 3/2 (D) 2

Second question using common data:
Q.56 The variance of the random variable Y is
(A) 1/2 (B) 2/3 (C) 1 (D) 2

Linked answer questions:
These questions are of problem solving type. A problem statement is followed by two questions based on the problem statement. The two questions are designed such that the solution to the second question depends upon the answer to the first one. In other words, the first answer is an intermediate step in working out the second answer. Each question in such ?linked answer questions? will carry two marks.

Example
Statement for Linked Answer Questions, for instance, for Questions 59 and 60 in Main Paper:

Consider a machine with a byte addressable main memory of 216 bytes. Assume that a direct mapped data cache consisting of 32 lines of 64 bytes each is used in the system. A 50x50 two dimensional array of bytes is stored in the main memory starting from memory location 1100H. Assume that the data cache is initially empty. The complete array is accessed twice. Assume that the contents of the data cache do not change in between the two accesses.

First question of the pair:
Q.59 How many data cache misses will occur in total?
(A) 48 (B) 50
(C) 56 (D) 59

Second question of the pair:
Q.60 Which of the following lines of the data cache will be replaced by new blocks in accessing the array for the second time?
(A) line 4 to line 11 (B) line 4 to line 12
(C) line 0 to line 7 (D) line 0 to line 8
