software engineering set 2 Detailed Explanation And More Example

Question : 1

Fail soft is

a) Trustworthiness with which a system or component can be modified to increase its storage or functional capacity

b) Pertaining to a system/component that automatically places itself in a safe operating mode in the event of a failure.

c) Pertaining to a system or component that continues to provide partial operational capability in the event of certain failures

d) None of these

Question : 2

In block diagrams, relationship between components is shown by

a) Boxes

b) Ovals

c) Circular

d) Lines/Arrows

Question : 3

Lehman’s Second 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 : 4

Ethnography is

a) It describes the basic entities in the design and relation between them.

b) Observational techniques used to understand social and organizational requirements.

c) It is based on the idea of developing an initial implementation, exposing it uses on requirement and refining it through many versions until an adequate system has been developed.

d) Based on an idea of developing an initial implementation, exposing this to uses comment and retiring it until and adequate system has been developed.

Question : 5

CASE (Computer Aided Software Engineering) is

a) A measure of the amount of work a system can perform

b) It provides automated support for software process.

c) Support individual process tasks

d) Set of tools to support a particular phase of software process such as design, implementation or testing:
