61. Which
of the following is not true with respect to a trackball and/or spaceball ?
I. A trackball is a two dimensional
positioning device while as a spaceball provides six degrees of freedom
II. Unlike the trackball a spaceball does not
actually move.
III. A trackball is a three dimensional
positioning device while as a spaceball provides six degrees of freedom.
(A) I & II
(B) II & III
(C) II only
(D) III only
Answer: D
Explanation:
A trackball is a pointing device consisting
of a ball held by a socket containing sensors to detect a rotation of the ball
about two axes. While a Trackball is a 2-D positioning device, a Space ball provides
six degrees of freedom. Unlike a trackball, a spaceball does not actually move.
Space balls are used for 3-D positioning, selection operations in V-R systems,
modelling and animation and other applications.
62. Which
of the following statement(s) is(are) true?
I. Two successive translations are additive.
II. Two successive rotations are additive.
III. Two successive scaling operations are
multiplicative.
(A) I and II
(B) I and III
(C) II and III
(D) All the above.
Answer: D
63. Given
below are three basic rules:
I. Squash and Stretch
II. Slow-in and Slow-out
III. To stage the action properly
These rules are applied in case of
(A) Rendering
(B) Morphing
(C) Animation
(D) All the above
Answer: C
64. Which
of the following points lies on the same side as the origin, with reference to
the line 3x+7y=2 ?
(A) (3, 0)
(B) (1, 0)
(C) (0.5, 0.5)
(D) (0.5, 0)
Answer: D
Explanation:
We have, 3x+7y=2
Putting origin (0,0) in the equation 3x+7y-2
3(0)+7(0)-2 = -2<0 (negative)
For (3, 0), (1, 0), (0.5, 0.5) the value of
expression is positive. But for (0.5, 0)the value of expression is same as that
for (0,0) i.e, negative
65. The
transformation matrix required for conversion of CMY colour model to RGB colour
model is given as
Answer: C
Explanation:
The RGB model is an additive model, i.e. the
colours present in the light add to form new colours.
The CMY (cyan-magenta-yellow) model is a
subtractive model appropriate to absorption of colours.
66. What
steps shall be required to rotate an object about the point P1 (as
shown in fig.1) and its placement such that what was at P1 is now
reduced and is at P2 (as shown in fig.2).
I. Translate P1 to origin
II. Scale as required
III. Rotate
IV. Translate to the final position P2.
(A) I,II and III
(B) II,III and IV
(C) I,III and IV
(D) All of the above
Answer: Marks given to all
Explanation:
Answer is I,II,III and IV
67. In
Unix, how do you check that two given strings a and b are equal ?
(A) test $a -eq $b
(B) test $a -equal $b
(C) test $a=$b
(D) Sh -C test $a==$b
Answer: C
Explanation:
Tests for a zero-length string: test -z string
Tests for a nonzero string length: test -n string
Tests two strings for equality: test string1 = string2
Tests two strings for inequality: test string1 != string2
Tests for a nonzero string length: test string

(B) Hardware abstraction layer
(C) Microkernel
(D) Process Manager
Answer: B

70. Translation
Look-aside Buffer(TLB) is
(A) a cache-memory in which item to be
searched is compared one-by-one with the keys.
(B) a cache-memory in which item to be
searched is compared with all the keys simultaneously.
(C) an associative memory in which item to be
searched is compared one-by-one with the keys.
(D) an associative memory in which item to be
searched is compared with all the keys
simultaneously.
Answer: D
