a) Object design models

b) Object interface design

c) Object oriented models

d) None of these

Question : 2

System engineering deals with

a) Software development only

b) Hardware development only

c) Software and Hardware development

d) Network development

Question : 3

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
