What is software?

• Physical parts of a computer

• A type of hardware component

• A set of programs and data that run on a computer

• The electricity powering a computer

What is the purpose of the Software Development Life Cycle (SDLC)?

• Install hardware

• Test code

• Guide software development

• Write code faster

What is Software Engineering?

• Repairing computer hardware

• Writing random code without a plan

• Applying engineering principles to software development

• Using software without understanding it

What is the main goal of software engineering ethics?

• To ensure software engineers act responsibly and professionally

• To avoid writing documentation

• To increase software sales

• To create software quickly

What is a software process?

• A tool used to fix bugs

• A programming language

• The speed at which software runs

• A set of activities to develop and maintain software

What is the Iterative Model?

• One-step development

• Development in repeated cycles

• Only for databases

• Hardware testing

What is the Waterfall model?

• Repeated short cycles

• Linear, step-by-step process

• Testing after deployment

• For mobile apps only

What is the Spiral Model?

• A linear process

• A risk-driven, iterative development model

• A model only for small projects

• A testing technique

What is the Incremental Model?

• Developing software in small, usable parts

• Building the whole system at once

• Testing after full development

• Designing hardware components

The Spiral Model primarily focuses on

• Rapid development

• Risk analysis

• Documentation

• Coding speed
