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. Spiral
The spiral model addresses high uncertainty and unfamiliar technologies through continuous risk evaluation. Teams lacking experience benefit from iterative prototyping and early risk analysis provided by spirals. Continu...
Answer: D. 4GT Model
The 4GT model heavily automates the coding phase leading to maintenance challenges if requirements shift. Generated code from high-level specifications is often difficult for human developers to modify later. This disadv...
Answer: A. SQL
SQL was invented by IBM and subsequently became the recognized ANSI and ISO standard for relational databases. Its declarative syntax allows developers to query and manage structured data efficiently across various platf...
Answer: C. planning, design, coding, testing
Extreme Programming incorporates planning, design, coding, and testing as framework activities. These core activities occur iteratively in short cycles to ensure rapid software delivery. Continuous execution of these fou...
Answer: A. on Lisp machine
Lisp machines are tied to artificial intelligence research rather than fourth-generation language origins. Fourth-generation languages originated from database query tools, report generators, and GUI creators. Lisp progr...
Answer: B. Barry Boehm
Barry Boehm initially introduced the spiral software lifecycle model in 1986. He designed it as a risk-driven process model for complex engineering projects. His work combined iterative development with systematic risk a...
Answer: D. All of the mentioned
Uncorrected software faults propagate through subsequent lifecycle phases and become increasingly expensive to fix. Finding a defect during later stages requires modifying design, code, and documentation simultaneously....
Answer: D. both in time & with acceptable quality
The fundamental goal of any software process is delivering working applications on time and with quality. Balancing delivery schedules against acceptable quality standards satisfies both client and business expectations....
Answer: C. Linear Model & Prototyping Model
The Incremental Model successfully combines the linear structured approach of the Waterfall model with prototyping. This hybrid nature allows teams to apply disciplined planning while delivering functional software in st...
Answer: B. Reduction in software development time
4GT models significantly reduce development time by automating code generation processes. Using Fourth Generation Techniques allows developers to specify requirements at high levels. Automated tools translate specificati...
Answer: C. scenarios
Extreme Programming captures user requirements as lightweight scenarios known as user stories. Scenarios provide concrete examples of how users interact with the system features. XP avoids heavy specification documents i...
Answer: C. 3, 2, 1
The definition phase focuses on what the software must accomplish. The development phase focuses on how the system is built. The support phase focuses on change and ongoing maintenance. Software engineering tasks are uni...
Answer: C. radial, angular
The spiral model uses radial dimensions to represent cumulative costs and angular dimensions for progress. These two geometric coordinates map out cost expenditure against project cycle progression clearly. Visualizing d...
Answer: A. It shows the process activities that are enacted
The static perspective of the Rational Unified Process shows process activities roles and artifacts enacted. It outlines who performs specific tasks and what work products are produced during development. This perspectiv...
Answer: B. Behavioral Model
Behavioral models are explicitly designed to depict the dynamic behavior and state changes of a software system. They illustrate how the system responds to external events and stimuli over elapsed operational time. Dynam...
