Qus:1
What do you understand by Information content and determinacy? Explain.
Answer:
Software may be
applied in any situation for which a prespecified set of procedural steps has
been defined. Information content and determinacy are important factors in
determining the nature of a software application. Content refers to the meaning
and form of incoming and outgoing information. Software that
Qus:2
Describe spiral model and its various task regions.
Answer:
Spiral model:
This model
couples the iterative nature of the prototyping with the controlled and
systematic aspects of the linear sequential model. It provides the potential
for rapid development of incremental versions of the software. Using the spiral
model, software is developed in a series of incremental releases. During early
Qus:3
Explain the various steps involved in establishing a reliability specification
and statistical testing.
Answer:
The steps involved in establishing a
reliability specification are as follows:
1) For each
identified sub-system, identify the different types of system failure, which
may occur and analyze the consequences of these failures.
2) From the
system failure analysis,
Qus:4
Differentiate object-oriented and function oriented approaches.
Answer:
Object-oriented
approaches:
Object-oriented design (OOD) transforms the analysis model created using
object-oriented analysis into a design model that serves as a blueprint for
software construction. Unlike conventional software design
Qus:5

process.
Answer:
Documents, which
may be produced to aid the maintenance process, include:
·
The requirements document and as
associated rationale.
·
A document describing the overall system
architecture.
·
For each program in the

Qus:6
Discuss the various test design methods used in real time software testing.
Answer:
Comprehensive
test case design methods for real-time systems have yet to evolve. However, an
overall four-step strategy can be proposed:
·
Task testing: The first step in the testing of
real-time software is to test each task independently. That is, white-box and
black-box tests are designed and executed for each task. Each task is
