📊 Software Engineering
Q. Lehman’s Fourth Law (Lehman and Belady 1985) is
  • (A) Organizational stability: Over a program’s lifetime, its rate of development is approximately constant and independent of the resources devoted to system development.
  • (B) Increase complexity: As an evolving program change, its strictures tend to become more complex. Extra resources must be devoted to preserving and simplifying the structure.
  • (C) Large program evolution: Program evolution is a self-regulating process.
  • (D) None of these
💬 Discuss
✅ Correct Answer: (A) Organizational stability: Over a program’s lifetime, its rate of development is approximately constant and independent of the resources devoted to system development.

Q. Human error is
  • (A) It is concerned with the design, evaluation, and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them.
  • (B) Extent to which a software product fulfills its purpose without wasting user’s time/ energy/degrading their morale.
  • (C) Human behavior that results in the introduction of faults into a system.
  • (D) None of these
💬 Discuss
✅ Correct Answer: (C) Human behavior that results in the introduction of faults into a system.
📊 Software Engineering
Q. Fault-tolerant architectures is
  • (A) The software and hardware system architectures that provide explicit support for tolerance, which includes software redundancy and fault- tolerance controller that detects problems and supports fault recovery*
  • (B) It is an initial step for requirements engineering process, includes the outline description of system, its use in an organization and recommending the system feasibility.
  • (C) Trustworthiness with which a system or component can be modified for use in applications or environments other than those for which it was specifically designed.
  • (D) None of these
💬 Discuss
✅ Correct Answer: (A) The software and hardware system architectures that provide explicit support for tolerance, which includes software redundancy and fault- tolerance controller that detects problems and supports fault recovery*
📊 Software Engineering
Q. Match the following:
A- Formal mathematical transformation:
B- Formal process model:
C-Formal Specifications:
D-Formal System development:
1- Here the formal mathema- tical representation of the system takes place.
2- It is a starting point for process analysis. It is abstract and only defines the principal process activities and deliverables.
3-Specifications expressed in a language whose vocabulary, syntax and semantics are formally defined.
4-It is more common to waterfall model, but here the development process is based on formal mathematical transformation of a system specification to an exactable program.
  • (A) A-1,B-2,C-3,D-4

  • (C) A-2,B-1,C-3,D-4
  • (D) A-1,B-3,C-2,D-4
💬 Discuss
✅ Correct Answer: (A) A-1,B-2,C-3,D-4
📊 Software Engineering
Q. Lehman’s First Law (Lehman and Belady 1985) is
  • (A) Continuing change: A program used in real-world environment must change necessarily or become progressively less useful in that environment.
  • (B) Increase complexity: As an evolving program change, its strictures tend to become more complex. Extra resources must be devoted to preserving and simplifying the structure.
  • (C) Large program evolution: Program evolution is a self-regulating process.
  • (D) None of these
💬 Discuss
✅ Correct Answer: (A) Continuing change: A program used in real-world environment must change necessarily or become progressively less useful in that environment.
📊 Software Engineering

  • (A) Extent to which a system or component performs a broad range of functions.
  • (B) The objective of an organization to achieve.
  • (C) Methods and techniques for converting data to or from graphic display via computers.
  • (D) None of these
💬 Discuss
✅ Correct Answer: (C) Methods and techniques for converting data to or from graphic display via computers.
📊 Software Engineering
Q. Intolerable risk is
  • (A) Ability of two or more systems, to exchange information and to use the information that has been exchanged.
  • (B) Time taken to respond to an event.
  • (C) Either the hazard not arises, if arise; it will not result in an accident.
  • (D) None of these
💬 Discuss
✅ Correct Answer: (C) Either the hazard not arises, if arise; it will not result in an accident.
