Set – I

1. What is SDLC? Explain different phases of SDLC

Ans: SDLC stands for Software Development Life Cycle. It is a structured framework that outlines the processes and activities involved in the development of software applications. The SDLC defines a series of phases that guide the entire software development process from inception to deployment

2. Explain the linear sequential life cycle model and spiral model in detail

Ans: Linear Sequential Life Cycle Model (also known as the Waterfall Model) and the Spiral Model in detail:  Linear Sequential Life Cycle Model (Waterfall Model): The Waterfall Model follows a sequential approach, where each phase flows in a linear manner from one to the next.

It is characterized by its rigid and structured nature. The different phases include: 

1. Requirements

 

3. How reliability in a software system can be achieved? Explain.

Ans: Achieving reliability in a software system is crucial to ensure that it consistently performs its intended functions correctly and without failure.

Here are some key considerations and approaches to achieving software system reliability: 

Requirements Engineering: Establish clear and comprehensive requirements through effective

 

 

Set – II

1. With the help of a diagram explain software reengineering process model.

Ans: I Software reengineering, also known as software renovation or software rejuvenation, involves modifying existing software systems to improve their quality, functionality, performance, or maintainability.

Here is a step-by-step explanation of typical software reengineering process model: 

Understanding the Existing System:  Analyze and comprehend the existing software system thoroughly. Identify its strengths, weaknesses, limitations, and areas requiring improvement.

 

2. What do you mean by testing? Differentiate between Black Box testing and White box testing.

Ans: Testing, in the context of software development, is the process of evaluating a software system or component to identify defects, errors, or gaps in functionality. It involves executing the software with test cases and comparing the actual results with expected results to ensure that the system behaves as intended. Testing helps in identifying and resolving issues before the software is deployed.

3. What is software quality assurance? Explain the activities that are carried throughout the project lifecycle

Ans: Software Quality Assurance (SQA) is a set of systematic activities and processes designed to ensure that software products meet specified quality standards and customer expectations. SQA aims to prevent defects, improve software development processes, and verify that the software functions correctly and reliably. It encompasses various activities that are carried out
