software engineering set 4 Detailed Explanation And More Example

Question : 1

Software design activities involved

a) System programming

b) System operations

c) Component design

d) Component development

Question : 2

A class room in a school is a

a) System

b) Sub-system

c) Module

d) None of these

Question : 3

Match the following: A- Formal mathematical transformation: B- Formal process model: C-Formal Specifications: D-Formal System development: 1- Here the formal mathematical representation of the system takes place. 2- It is a starting point for process analysis. It is abstract and only defines the principal process activities and deliverables. 3-Specifications expressed in a language whose vocabulary, syntax and semantics are formally defined. 4-It is more common to waterfall model, but here the development process is based on formal mathematical transformation of a system specification to an exactable program.

a) A-1,B-2,C-3,D-4

b) A-4,B-2,C-3,D-1

c) A-2,B-1,C-3,D-4

d) A-1,B-3,C-2,D-4

Question : 4

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 : 5

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 : 6

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
