BCA5030, SOFTWARE ENGINEERING
Qus:1
What is The Need for a Business Model in Software Engineering?
Answer: Software engineering faces several dilemmas. It has
comprehensive goals, but limited tools. It demands broad perspectives, but
depends on narrowly focused practitioners. It places a high premium on quality,
but often has insufficient inputs to its problem-solving process. As a field,
software engineering has yet to define theories and frameworks that adequately
combine the disciplines of
Qus:2
a) What are the different levels of software reuse?
b)
What are the aspects of software reuse?
Answer: The design process in most engineering disciplines is
based on component reuse. Mechanical or electrical engineers do not specify a
design in which every component has to be manufactured specially. They base
their design on components that have been tried and tested in other
Qus:3
What is meant by Architectural Design? Explain.
Answer: Large systems can be decomposed into sub-system that
provides some related set of services. The initial design process of
identifying this subsystem and establishing a framework for sub-system control
and communication is called Architectural design.
Architectural design comes before
detailed system specification, it should not include any design information.
Architectural design is necessary to structure and organize the specification.
This model is the starting point for the specification of the various parts of
the system. There
Qus:4
What are the different phases of Rapid Application Development model?
Answer: Rapid Application Development (RAD) is an incremental
software development process model that emphasizes an extremely short
development cycle. The RAD model is a high speed adaptation of the linear
sequential model in which the rapid development is achieved by using component
Qus:5
Explain Top-down Integration Testing and Bottom-up Integration Testing.
Answer: Top-down integration testing is an incremental approach to
construction of program structure. Modules are integrated by moving downward
through the control hierarchy, beginning with the main control module (main
program). Modules subordinate (and ultimately subordinate) to the
Qus:6
What do you mean by Customer Driven software development?
Answer: It is a truism that, in a customer-focused economy, software
engineering must also be customer driven. This section considers some
characteristics and techniques typical of a customer-driven software
development environment. These include:

(b)
Limited animation
(c)
Rotoscoping
Answer: (a) Full animation refers to the process of producing
high-quality traditionally animated films, which regularly use detailed
drawings and possible movement. Fully animated films can be done in a variety
of styles, from more realistically animated works such as those produced by the
Walt Disney studio (Beauty and the Beast,
Aladdin, Lion King) to the more 'cartoony'
Qus:2
Discuss Bresenham’s line drawing algorithm.
Answer:
The Bresenham's line-drawing
algorithm is based on drawing an approximation of the true line. The true line
Qus:3
Discuss mid-point circle algorithm.
Answer: In computer graphics, the midpoint circle algorithm is an
algorithm used to determine the points needed for drawing a circle. The
algorithm is a variant of Bresenham's line algorithm, and is thus sometimes
known as Bresenham's circle algorithm.
Let's simplify the
Qus:4
Explain polygon clipping.
Answer: A polygon is usually defined by a sequence of vertices and
edges. If the polygons are unfilled, line-clipping techniques are sufficient
however, but if the polygons are filled, the process in more complicated. A
polygon may be fragmented into several polygons in the clipping process, and
the original colour associated with each one. The Sutherland-Hodgeman clipping
algorithm clips any polygon against a convex clip polygon. The Weiler- Atherton

Discuss the parametric spline curves
Answer: Parametric equations can be used to generate curves that are
more general than explicit equations of the form

Explain the different types of plotter.
Answer: Plotters are special output devices used to produce hard
copies of large graphs and designs on paper. Plotters are often used for the
