71. Which of the following is characteristic of an MIS?

  • Option : B
  • Explanation :
    Characteristic of an Management Information System(MIS) is draws on diverse yet predictable data resources to aggregate and summarize data. Other characteristic of MIS are as follows:
  • Management-oriented
  • Management-directed Integrated
  • Common data flows
  • Heavy planning-element
  • Sub System concept
  • Common database
  • User friendly/Flexibility
  • Information as a resource
  • Provides guidance in identifying problems, finding and evaluating alternative solutions, and selecting or comparing alternatives. It is a characteristics of decision support system(DSS).
  • High volume, data capture focus, efficiency of data movement, processing and interfacing different TPS. These are the characteristics of transaction processing system(TPS)
  • So, option (B) is correct.

73. Consider the following game tree in which root is a maximizing node and children are visited left to right. What nodes will be pruned by the alpha-beta pruning ?

  • Option : B
  • Explanation :
    We have to maximize A and minimize B and C. Minimum of B is 3 and C is 2 But max from B is 12 and max from C is 15. So, there is no need of further expanding H and I. Because whatever value their successor will produce will be immaterial. Hence H I are pruned.So, Option (B) is correct.

  • Option : C
  • Explanation :
  • A software program that infers and manipulates existing knowledge in order to generate new knowledge is known as Inference engine.
  • A data dictionary is a collection of descriptions of the data objects or items in a data model for the benefit of programmers and others who need to refer to them.
  • Control strategies are specific action plans for bringing a process back into control.
  • Reference is what relates words to the world of objects on whose condition the truth of sentences hinges and it is natural to wonder what sorts of relations underlie the reference relation-to wonder, that is, what constitutes the mechanism of reference.
