software engineering set 5 Detailed Explanation And More Example

Question : 1

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 : 2

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 : 3

Manufacturing phase is

a) Period in the software life cycle in which a software product is created from design documentation and debugged.

b) Period in the software life cycle in which a software product is integrated in its operational environment, and tested in this environment to ensure it performs as required.

c) Period in the software life cycle during which the basic version of a software product is adapted to a specified set of operational environments and is distributed to a customer base.

d) None of these

Question : 4

Corrupting failure is

a) Maintenance performed to correct faults in hardware or software

b) A failure of software-controlled systems in convenience, but there are source systems where system failure is resulted in significant critical losses.

c) Failure that corrupts system state or data

d) None is true

Question : 5

Use of Email instead of post & telegraph is due to

a) Technology changes

b) Requirement changes

c) Users access

d) All the above

Question : 6

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.
