Question 21. Software design specification

Are statements, made in natural language to specify the system specification and constraints
An abstract description of software design, which is an extension of system requirement specification
Discusses the market policy of the system
None of these

Discuss Question

Answer: Option B. -> An abstract description of software design, which is an extension of system requirement specification
Answer: (b)

Question 22. ROCOF (Rate of failure occurrence) is

The probability that the system will cause an accident
Extent to which a system or component can function correctly in the presence of invalid inputs or stressful environment conditions.
The frequency of occurrence with which unexpected behavior is likely to occur
None of these

Discuss Question

Answer: Option C. -> The frequency of occurrence with which unexpected behavior is likely to occur
Answer: (c)

Question 23. In Bottom-up integration

The low-level components of a system are integrated and tested before the higher-level components have been developed
The testing process starts with modules at lower levels in the hierarchy and works up the hierarchy of modules until the final module is tested.
An event driven control system, where an event is broadcasted to each subsystem and any sub-system that can handle that event responds to it.
Control starts of the top of a sub routine hierarchy and through sub routine calls passes to lower levels.

Discuss Question

Answer: Option A. -> The low-level components of a system are integrated and tested before the higher-level components have been developed
Answer: (a)

Question 24. It is intended to find inconsistencies between a program and its specification. These inconsistencies are usually due to program faults or defects.

Discuss Question

Answer: Option C. -> Defect testing
Answer: (c)

Question 25. Under estimate of cost is

Technology risk
People risk
Estimation risk
Organizational risk

Discuss Question

Answer: Option C. -> Estimation risk
Answer: (c)

Compatibility
Compactness
Code
Communication

Discuss Question

Answer: Option B. -> Compactness
Answer: (b)

Question 27. Feasibility studies

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
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.
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.
None of these

Discuss Question

Answer: Option 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.
Answer: (b)

Question 28. Evolvability is

Trustworthiness with which a system or component can be modified to take advantage of new software or hardware technologies.
An error of some kind or an unexpected event occurs during the execution of a program
Here the objective of the process is to work with uses to explore their requirement and deliver a final system.
Possible loss or harm in computing system.

Discuss Question

Answer: Option A. -> Trustworthiness with which a system or component can be modified to take advantage of new software or hardware technologies.
Answer: (a)

Question 29. Probability of an accident arising because of hazard is minimum subject of other costs
