Software Engineering is part of Computer Science and holds 1,969 questions with answers, free to read and with no account needed.
Questions from this area appear in PPSC, FPSC, NTS, KPPSC and SPSC papers. Each guide explains how that paper is built and which subjects carry it.
Attempt each question before revealing the answer, and keep a note of the ones you get wrong — those are the topics worth reading about properly. If an answer looks wrong, there is a link to report it on every question.
Answer: A. Doesn’t work well for smaller projects
The spiral model requires extensive documentation and risk analysis that burden smaller, straightforward projects. Smaller projects benefit from lightweight methodologies rather than complex risk-driven development frame...
Answer: D. Structural Model
Structural models depict the static nature of a system highlighting components and their permanent relationships. Unlike dynamic models structural views ignore runtime behavior and temporal execution sequences. Object di...
Answer: B. Three
Scrum is traditionally described in academic literature as having three distinct phases including pre game and post game. These phases structure the overall lifecycle of an agile software development initiative from plan...
Answer: C. reusability
Reusability is an internal quality attribute measuring component adaptability across projects. Internal qualities focus on code structure and maintainability rather than external behavior. Modular components designed wit...
Answer: A. Translation
Translation is not recognized as a standard category of maintenance change in software engineering. The four standard maintenance categories are correction, adaptation, enhancement, and prevention. Support phase activiti...
Answer: C. Both RAD & Prototyping Model facilitates reusability of components
Both RAD and prototyping models facilitate the reusability of software components. Rapid application development relies on pre-built modules to speed delivery. Prototyping reuses code snippets and components to build qui...
Answer: C. Both RAD & Iterative Enhancement
Rapid application development and iterative enhancement both support incremental delivery for existing software versions. Iterative enhancement refines existing codebases while rapid development accelerates feature deplo...
Answer: A. Structural perspective
The structural perspective of system modeling reveals static architecture including data and component layouts. Structural models organize system elements showing how classes modules and databases interrelate. This persp...
Answer: D. Nine
Unified Modeling Language historically established nine primary notations for visualizing software system designs. These diagrams covered structural and behavioral aspects allowing comprehensive architectural documentati...
Answer: A. Reliability
Reliability measures the probability that software performs intended functions without failure. Higher reliability means the system remains available and operational for specified periods. Minimizing runtime crashes dire...
Answer: D. Both Incremental and Iterative Development
Agile methodologies release software in small, working pieces through incremental development cycles. At the same time, they constantly refine features and requirements through iterative feedback loops. Combining both ap...
Answer: A. Use Case, Sequence
Use case and sequence diagrams illustrate behavioral interaction modeling in UML. Use cases capture system functionality from user perspectives. Sequence diagrams show message exchanges between objects over time. Behavio...
Answer: C. Generic, Customised
Generic products target a broad commercial market while customized products fulfill specific client requirements. This dichotomy captures the fundamental business models driving software product creation and distribution...
Answer: D. All of the mentioned
Usability metrics encompass multiple dimensions including learnability efficiency and productivity gains. Measuring the intellectual skill required to learn a system evaluates its user-friendly design. Time to efficiency...
Answer: C. Boundary
Boundary classes model the interface between the software system and its external environment including users. They encapsulate user interface logic and ensure that interactions with human actors are handled cleanly. Sep...
