UGC NET Paper 2 Computer Science – Software Engineering PYQ: Software Design

The steps for analysis and design of object oriented system:
(A) Draw interaction diagrams
(B) Draw state chart and object diagram
(C) Draw use case and activity diagram
(D) Draw component and deployment diagram
(E) Draw class diagram

Given below are two statements:
Assertion A: Cohesion is a qualitative indication of the degree to which a module can be written more compactly and is able to complete its function in a timely manner.
Reason R: Cohesion is a qualitative indication of the degree to which a module is connected to other modules and the outside world.
In the light of the above statements, choose the correct answer from the options given below:

Modules X and Y operate on the same input and output, then the cohesion is

Arrange the following types of Cohesion from best to worst type.
A. Logical Cohesion
B. Sequential Cohesion
C. Communication Cohesion
D. Temporal Cohesion
E. Procedural Cohesion
Choose the correct answer from the options given below:

Which of the following UML diagrams has a static view?

Which of the following statements is/are TRUE?
P: In software engineering, defects that are discovered earlier are more expensive to fix.
Q: A software design is said to be a good design, if the components are strongly cohesive and weakly coupled.
Select the correct answer from the options given below:

Software coupling involves dependencies among pieces of software called modules. Which of the following are correct statements with respect to module coupling?
P: Common Coupling occurs when two modules share the same global data.
Q: Control Coupling occurs when modules share a composite data structure and use only part of it.
R: Content Coupling occurs when one module modifies or relies on the internal working of another module.

Match each UML diagram in List-I with the appropriate description in List-II:
List-I
(a) State Diagram
(b) Use-Case Diagram
(c) Class Diagram
(d) Activity Diagram
List-II
(i) Describes how the external entities (people, devices) can interact with the system
(ii) Used to describe the static or structural view of a system
(iii) Used to show the flow of a business process, the steps of a use-case or the logic of an object behaviour
(iv) Used to describe the dynamic behaviour of objects and could also be used to describe the entire system behaviour

Coupling is a measure of the strength of the interconnections between software modules. Which of the following are correct statements with respect to module coupling?
P: Common coupling occurs when one module controls the flow of another module by passing it information on what to do.
Q: In data coupling, the complete data structure is passed from one module to another through parameters.
R: Stamp coupling occurs when modules share a composite data structure and use only parts of it.

A software design pattern often used to restrict access to an object is:

Consider the following statements regarding software architecture:
S1: Coupling is a measure of how well the things grouped together in a module belong together logically.
S2: Cohesion is a measure of the degree of interaction between software modules.
S3: If coupling is low and cohesion is high then it is easier to change one module without affecting others.
Which of the following is true?

A software design pattern used to enhance the functionality of an object at run-time is:

Module design is used to maximize cohesion and minimize coupling. Which of the following is the key to implement this rule?

The design concept 'Refinement' is a:

A software design is highly modular if:

Cohesion is an extension of:
