31. In CRC based design, a CRC Team consists of: (a)one or two users representatives (b)several programmers (c)project co-ordinators (d)one or two system analysts Codes:

  • Option : C
  • Explanation : In Critical review committe(CRC) based design, a CRC Team consists of one or two users representatives, project co-ordinators, one or two system analysts. There is no programmer in Critical review committe. So, option (C) is correct.

32. The end points of a given line are (0, 0) and (6, 18). Compute each value of y as x steps from 0 to 3, by using equation of straight line:

  • Option : A
  • Explanation : A is the ans equation of line passing through 2 points (x1,y1) ,(x2,y2) is

    y-y1=(y2-y1)*(x-x1)/(x2-x1)

    so here eqn of line is y-0=(18-0)(x-0)/(6-0) =>y=3x

    so when x=0 y=0

    x=1 y=3

    x=2 y=6

    x=3 y=9 hence ans is A

34. Javascript and Java has similar name because __________ is/are true.
(a)Javascript syntax is loosely based on Java’s syntax
(b)Javascript is stripped down version of Java
(c)Java and Javascript are originated from Island of Java
Codes:

  • Option : A
  • Explanation :
    Javascript and Java has similar name because Javascripts syntax is loosely based on Java’s syntax. Javascript is not the stripped down version of Java and Java and Javascript are originated from Island of Java also wrong. So, option (A) is correct.

35. Which of the following statements are true with reference to the way of describing XML data?
(a)XML uses DTD to describe the data
(b)XML uses XSL to describe the data
(c)XML uses a description node to describe the data
Codes:

  • Option : D
  • Explanation :
    XML uses Document Type Definition(DTD) to describe the data. DTD is specified document defining and constraining definition and XML uses a description node to describe the data. Extensible Stylesheet Language(XSL) is used to transform and render the XML document. Statement (a) and (c) are correct. So, option (D) is correct.
