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. User’s end
Beta testing is performed by actual end users at their own operating sites. This user-driven testing phase gathers feedback from real world usage environments. Deploying beta versions helps uncover environmental bugs mis...
Answer: C. 80, 20
Pareto's principle states that roughly 80 percent of problems stem from 20 percent of causes. This 80/20 rule appears frequently in quality management and defect analysis. Variables x and y correspond directly to 80 and...
Answer: A. maintenance
Effective testing reduces long-term software maintenance costs significantly. Finding and fixing bugs early prevents expensive production failures. Quality assurance minimizes the effort required to patch deployed system...
Answer: C. Non-Comment Source Statement
Non comment source statement measures source code size by counting executable lines excluding comments. Static analysis tools calculate metric ratios using non-comment source statements as a standard size base. Excluding...
Answer: C. Software failure
Software failure occurs whenever an executable system fails to meet established requirements or expectations. Discrepancies between expected user outcomes and actual system behavior define runtime software failures. This...
Answer: D. Both Alpha and Beta
Both alpha and beta testing prioritize how the customer uses the system in real world operational environments. Alpha testing occurs at the developer site with users whereas beta testing happens at customer locations. Th...
Answer: C. efficiency
Efficiency in ISO 9126 includes sub-characteristics related to resource utilization and time behavior. This category evaluates how well software utilizes hardware resources and executes tasks. Optimizing execution time a...
Answer: B. Mean time to failure
MTTF stands for Mean Time To Failure, a standard reliability metric. It measures the average expected operating time between software system failures. Higher MTTF values indicate more dependable and robust software syste...
Answer: B. Black Box Testing
Boundary value analysis is a component of black-box testing categories. It tests the edges of input domains without looking at internal source code. Testers choose boundary values because errors frequently cluster at ran...
Answer: A. Unit testing
Unit testing evaluates the smallest testable software components such as individual classes or functions. Isolating encapsulated objects allows developers to verify internal logic without external dependencies. Focusing...
Answer: D. independent test group
ITG stands for Independent Test Group representing a specialized team separate from developers. Independence ensures unbiased evaluation and rigorous testing of software products before release. This organizational separ...
Answer: A. Run chart
A run chart displays data points over time, while a control chart specifically includes upper and lower control limits to monitor process stability.
Answer: D. all of the mentioned
A debugging program operating alongside software examines memory registers stops execution and searches variable references. These comprehensive debugging features allow engineers to trace execution paths and isolate roo...
Answer: D. Appraisal
Appraisal costs cover activities like inspections and testing used to evaluate software quality. Organizations spend resources assessing products to ensure they meet specified requirements. Detecting defects early throug...
Answer: B. pattern recognition game playing
Pattern recognition game playing is a general-purpose application, not embedded software. Embedded software runs on dedicated hardware for specific control and monitoring tasks. Games typically require general operating...
