41. If S1 is total number of modules defined in the program architecture, S3 is the number of modules whose correct function depends on prior processing then the number of modules not dependent on prior processing is :

  • Option : B
  • Explanation :
    S1 is total number of modules defined in the program architecture. S2 is total number of modules whose correct function depends on the source of data input or that produces data to be used elsewhere. S3 is the number of modules whose correct function depends on prior processing. Program structure (D1) is defined as if architectural design was developed using a distinct method then D1 is 1 otherwise it is zero. Module independence: D2 = 1 - (S2 / S1) Module not dependent on prior processing: D3 = 1 - (S3 /S1) So, option (B) is correct.

42. The ________ model is preferred for software development when the requirements are not clear.

  • Option : C
  • Explanation :
  • The Evolutionary Model model is preferred for software development when the requirements are not clear.
  • In a Waterfall model, each phase must be completed before the next phase can begin
  • Rapid Application Development uses minimal in favor of rapid prototype(functionally equivalent component of product)
  • Rational Unified Processdivides the development process into four distinct phases: business modeling, analysis and design, implementation, testing, and deployment.
  • So, option (C) is correct.

43. Which of the following is not included in waterfall model?

  • Option : B
  • Explanation :
    Waterfall model have following phases:
  • Requirement Analysis
  • System Design
  • Implementation
  • Testing
  • Deployment
  • Maintenence
  • It doesn't include Risk analysis. So, option (B) is correct.

45. The extent to which a software tolerates the unexpected problems, is termed as:

  • Option : D
  • Explanation :
  • The extent to which a software tolerates the unexpected problems, is termed as Robustness.
  • Accuracy is the degree to which the result of a measurement, calculation, or specification conforms to the correct value or a standard
  • Reliability is the degree to which the result of a measurement, calculation, or specification can be depended on to be accurate.
  • Correctnessthe quality or state of being free from error; accuracy.
  • So, option (D) is correct.
