software engineering set 4 Detailed Explanation And More Example

Question : 1

Lehman’s Fourth Law (Lehman and Belady 1985) is

a) Organizational stability: Over a program’s lifetime, its rate of development is approximately constant and independent of the resources devoted to system development.

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

In Call-return control model

a) The low-level components of a system are integrated and tested before the higher-level components have been developed.

b) 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.

c) 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.

d) Control starts of the top of a sub routine hierarchy and through sub routine calls passes to lower levels

Question : 3

Software implementation is

a) It is concern with modification of existing system to meet changing requirements.

b) It is a process of converting system specifications into an executable system.

c) It analyzes and checks system representation such as the requirements document, design diagrams and program source code.

d) None of these

Question : 4

An object-oriented model of system architecture structures the system into a set of loosely coupled objects with well-defined interfaces.

a) Object design models

b) Object interface design

c) Object oriented models

d) None of these

Question : 5

Auditable is

a) Here each component has a unique name and an associated set of attribute, which differs for each version of component

b) Extent to which a software system records information concerning transactions performed against the system

c) Extent to which a system or component is operational and accessible when required for use

d) They are used to describe the over all behavior of the system

Question : 6

Role is

a) Avoiding catastrophic moment

b) Ease with which a system or component are modified to fit the problem area.

c) It is a bounded area of responsibility

d) None of these
