Waterfall Model

The Waterfall Model is a type of ______.

• a. Iterative model

• b. Linear-sequential model

• c. Agile model

• d. Spiral model

Which of the following is an example of front-end development?

• Algorithm optimization
• Server configuration
• User interface design
• Database management

Which stage of the Waterfall model is an essential precursor to development?

• Deployment Stage
• Requirement Gathering Stage
• Design Stage
• Testing Stage

What is the first step of the Waterfall model?

• Generate the system requirements
• Design the user interface
• Develop the back-end components
• Test the application features

What is the main output of the Design phase?

• a. Program code

• b. Prototype

• c. User feedback

• d. Deployed software

Bugs and errors are found and fixed during which phase?

• a. Design

• b. Testing

• c. Implementation

• d. Maintenance

What is the difference between front-end and back-end development?

• Front-end is for testing, back-end is for design
• Front-end is running the application behind the scenes, back-end is building components that interact with users
• Front-end is for deployment, back-end is for development
• Front-end is building components that interact with users, back-end is running the application behind the scenes

What is the role of back-end development in the SDLC?

• Designing the user interface
• Running the application behind the scenes
• Testing the application features
• Building components that interact with users

The Waterfall Method is called “Waterfall” because:

• a. It goes back and forth like flowing water

• b. Phases can be repeated anytime
  

• c. Phases flow downward from one step to the next

• d. It has no beginning and no end

What is the purpose of the System Development Life Cycle (SDLC) like the Waterfall model?

• To outline, design, develop, test, and deploy an information system or software product
• To generate system requirements
• To build user interface components
• To run the application behind the scenes
