Q1. Explain different kinds of software applications.[10]
Answer.
Different kinds of software applications
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 applications can be neatly compartmentalized into different categories.
System software: System software is a collection of programs written toservice other programs.
Some system
Q2. What are the Limitations of waterfall model? Explain [10]
Answer.
Limitations of waterfall model
1. The linear sequential model or waterfall model assumes the requirement of a system which can
be frozen (baseline) before the design begins. This is possible for systems designed to automate an
existing manual system.
Q3. Describe the operation of Data flow model with the help of a block diagram [10]
Answer.
Operation of Data flow model
Data-flow model is a way of showing how data is processed by a system. At the analysis level, they
should be used to model the way in which data is processed in the existing system. The notations
used in these models represents

2. Q4. Explain the various activities involved in Software Reengineering process model [10]
Answer.
Activities involved in Software reengineering process model
This means that each of the activities presented as a part of the paradigm may be revised. For any
particular cycle, the process can terminate after any one of these activities.
Inventory analysis: Every software organization should have an inventory of all applications. The
inventory can
Q5. Explain Black-Box testing in detail [10]
Answer.
Black-Box testing
Black-box testing, also called behavioural testing, focuses on the functional requirements of the
software. That is, black-box testing enables the software engineer to derive sets of input conditions
that will fully exercise all functional requirements for a program. Black-box testing is not an
alternative to white-box techniques. Rather, it is a complementary approach that is likely to uncover
a different class of errors than white-box methods. Black-box testing attempts to find errors in the
following categories:
Q6. With the help of bock diagram explain how global problem solving can apply a software-
driven approach to enhance the efficiency of problem solving. [10]
Answer.
Global problem solving on software-driven approach
Problem solving consists of using generic or ad hoc methods, in an orderly manner, for finding
solutions to problems. Some of the problem-solving techniques developed and used in artificial
intelligence, computer science, engineerin
