software engineering set 3 Detailed Explanation And More Example

Question : 1

Agents are

a) Quality measures that address how easily a system can evolve or migrate

b) Piece of software that acts to accomplish tasks on behalf of its user

c) A quantitative option analysis that allows the cost of various options to be computed, and options can be compared on objective basis

d) Extent to which a software system or component allows for or supports anonymous transactions

Question : 2

Evolutionary prototyping 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 : 3

Procedural interface

a) Trustworthiness with which a system are transferred from one hardware environment to another

b) Here one sub system encapsulates a set of procedures, which can be called by other sub-systems.

c) It is concerned with studying existing process to understand the relationship between different parts of the process.

d) None of these

Question : 4

In system models, object is

a) An entity that has a state and defined set of operations that operates on that state

b) Software program

c) Programming language, that develops any given program

d) None of these

Question : 5

Cost of maintenance

a) Process of estimating the costs associated with software development projects that include the effort, time, and labor required.

b) Overall cost of maintaining a computer system that includes the costs associated with personnel/training/ maintenance of hardware and software/ requirements growth.

c) Overall cost of operating a computer system that includes the costs associated with personnel / training / system operations.

d) Overall cost of a computer system to an organization that includes the costs associated with operating/ maintaining the system, and the lifetime of operational use of the system.

Question : 6

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
