software engineering set 5 Detailed Explanation And More Example

Question : 1

Parkinson’s Law is

a) The cost is determined by available resources rather than by objective assessment.

b) A program used in real-world environment must change necessarily or become progressively less useful in that environment.

c) As an evolving program change, its strictures tend to become more complex.

d) Program evolution is a self-regulating process.

Question : 2

Lehman’s Third 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

Question : 3

Software migration and evolution is

a) Time-period that begins when a software product is conceived and ends when the software is no longer available for use.

b) Adaptive maintenance, performed to make a computer program usable in a changed environment.

c) A simplified description of a software process that is presented from a particular perspective.

d) None of these

Question : 4

Use of Email instead of post & telegraph is due to

a) Technology changes

b) Requirement changes

c) Users access

d) All the above

Question : 5

Exposure is

a) Trustworthiness with which a system or component can be modified to take advantage of new software or hardware technologies.

b) An error of some kind or an unexpected event occurs during the execution of a program

c) Here the objective of the process is to work with uses to explore their requirement and deliver a final system.

d) Possible loss or harm in computing system.

Question : 6

Software maintenance is

a) It is the general process of changing system after it has been delivered. The changes can be to correct coding error to correct design error, or adding new components to system.

b) It is concerned with deriving a numeric value for some attribute of a software product or a software process.

c) It is any type of measurement, which relates to software system, process and related documentation.

d) None of these
