Qus:1 Explain the
following
a)
System software
b)
Embedded software
Answer:
a)System
software:
System software
is a collection of programs written to service other programs. Some system
software process complex information structures. Other systems applications
process largely indeterminate data. It is characterized by heavy interaction
with hardware, heavy usage by multiple users, concurrent operation that
requires scheduling, resource sharing, and sophisticated process management,
complex data structures and multiple external interfaces.
Q2.
List the limitations of the linear sequential model?
Answer:
The Serial or
Linear Sequential Development Model:
This Model also
called as the Classic life cycle or the Waterfall model. TheLinear sequential
model suggests a systematic sequential approach tosoftware development that
begins at the system level and progressesthrough analysis, design, coding, testing,
and support. Figure shows thelinear sequential model for software engineering
Modeled after aconventional engineering cycle, the linear sequential model has
thefollowing activities:
Q3
What do you mean by object –oriented design? List the characteristics of an
object-oriented design (OOD).
Answer.
Object Oriented
Design:
Object –oriented
design is a design strategy based on information hiding. It differs from the
function approach to design in that it views a softwaresystem as a set of
interacting objects, with their own private state, ratherthan as a set of
functions that share a global state.
Q4.
Write a note on Prototyping Model.
Answer:
The Prototyping
Model:
Prototypes are
used in many engineering disciplines. Although whatconstitutes a software or
information systems prototype cannot be uniquelydefined, there are three
readily identifiable characteristics. The prototypeshould be able to:
·
Be
a temporary system
Qus:5 Explain
the following
a) Reverse engineering
b) Forward engineering
c) Data reengineering
d) Redocumentation
e) Restructuring
Answer:
a)
Reverse engineering:
Reverse engineering refers to the attempt to extract and abstract designinformation
from the existing system’s source code; in other words, it attempts to recover
the design implemented in the code. Reverse engineering uses the information
about the system’s scope and functionality provided by the inventory analysis.
Qus:6
What are the factors affecting the status or interpretation of differences in
software engineering?
Answer:
Factors
affecting the status or interpretation of differences in software engineering:
·
The simultaneity
factor: Some
differences can appear contradictory when they occur simultaneously, but are
actually complementary when placed in sequential order on a timeline. For
example, consider a false dichotomy such as whether analysis or design, process
or architecture is more important in software development. Of course, when
