Software Design MCQs
This page provides you software multiple-choice questions that help with many exams like Semester, Gate, Railway, and ISRO.
Q.1 Which of the following tools is used for structured designing?
Program flowchart
Structure chart
Data-flow diagram
Module
Explanation
A structure chart is a top-down modular design tool used in structured design to show the hierarchy and relationship between different software modules.
Q.2 Who is responsible for designing and implementing database structures?
Programmers
Project managers
Technical writers
Database administrators
Explanation
Database Administrators (DBAs) are specialized professionals responsible for the logical and physical design, implementation, and management of database systems.
Q.3 Structured design is primarily based on which principle?
High level
Divide and conquer
Unit wise
None of these
Explanation
Structured design follows the ‘divide and conquer’ strategy, breaking a complex problem into smaller, more manageable sub-systems.
Q.4 During the design phase, which of the following is a primary area of concern?
Architecture
Data
Interface
All of these
Explanation
System design must simultaneously address the software architecture, the internal data structures, and the user/system interfaces.
Q.5 In which system design approach are the individual parts of the system defined in detail before being integrated?
Bottom up design
Top down design
Both A & B
All of these
Explanation
Bottom-up design focuses on creating the lowest-level components first and then combining them into larger, more complex structures.
Q.6 Which of the following are characteristics of a good software design?
Implements all explicit requirements
Accommodates all implicit requirements
Address stakeholder needs
All of these
Explanation
A quality design must satisfy both the explicitly stated requirements from the model and the implicit expectations of the users and stakeholders.
Q.7 The decomposition of a system into smaller parts to understand its sub-systems is known as?
Top-down design
Bottom up Design
Both A & B
None of these
Explanation
Top-down design starts with a high-level overview and progressively breaks it down into smaller, detailed levels of sub-components (decomposition).
Q.8 Which design phase transforms structural elements into a procedural description of software components?
Procedural Design
Bottom up Design
Data Design
None of these
Explanation
Procedural design details the internal logic and algorithmic steps required for individual software modules to function.
Q.9 Which option does NOT define Function-Oriented Software Design?
It consists of module definitions
Modules represent data abstraction
Focuses on processes
None of these
Explanation
In Function-Oriented design, modules represent processes or functions; data abstraction is a core concept of Object-Oriented design instead.
Q.10 The Java programming language generally follows which design methodology?
Bottom Up Design
Top Down Design
Function Design
None of these
Explanation
As an Object-Oriented language, Java typically utilizes a bottom-up approach by defining classes and objects that are later integrated.
Q.11 The C programming language generally follows which design approach?
Bottom Up Design
Top Down Design
Function Design
None of these
Explanation
C is a procedural language that traditionally follows a top-down design flow, breaking the main problem into functions.
Q.12 FORTRAN is a programming language that typically follows which design approach?
Bottom Up Design
Top Down Design
Function Design
None of these
Explanation
FORTRAN is a procedural language designed for scientific computing that historically utilizes a top-down design methodology.
Q.13 The Bottom-up model is based on which logical approach?
Composition
Decomposition
Both A & B
None of these
Explanation
Bottom-up design relies on composition, which is the act of assembling complex systems from existing or pre-built components.
Q.14 The Top-Down model is based on which logical approach?
Composition
Decomposition
Both A & B
None of these
Explanation
Top-down design relies on decomposition, the process of breaking a single complex entity into its simpler constituent parts.
Q.15 Which of the following is a characteristic of a well-formed design class?
Primitiveness
High cohesion
Low coupling
All of the above
Explanation
Ideal software classes should be highly cohesive (perform specific tasks) and loosely coupled (minimize dependencies on other classes).
Q.16 Which of the following is a 'golden rule' for user interface design?
Place the user in control
Reduce the user's memory load
Make the interface consistent
All of the given options
Explanation
According to Theo Mandel, these rules ensure that an interface is intuitive, efficient, and easy to navigate for the user.
Q.17 Which of the following is NOT an activity of user interface design?
User/task analysis
Interface design
Knowledgeable, frequent users
Environment analysis
Explanation
Knowledgeable, frequent users’ is a category of users, whereas the others are specific analytical phases of the design process.
Q.18 What does the acronym HLD stand for in the system development lifecycle?
High level Detection
High level Design
High level Division
None of these
Explanation
HLD (High Level Design) describes the overall system architecture, including the database design and module interactions.
Q.19 What does the acronym LLD stand for in software engineering?
Low level Detection
Low level Design
Low level Division
None of these
Explanation
LLD (Low Level Design) provides the detailed logic, data structures, and algorithms for each individual component of the software.
Q.20 Low Level Design (LLD) is also commonly referred to as?
Macro Level System Design
Micro Level System Design
High level Division
None of these
Explanation
LLD is called Micro Level Design because it focuses on the minute internal details and implementation specifics of individual modules.
