Final answer:
Rapid Application Development (RAD) is an approach used to quickly develop software applications through prototyping and iterative development.
Step-by-step explanation:
Rapid Application Development (RAD) is an approach used to quickly develop software applications. It focuses on prototyping and iterative development, allowing for the rapid creation and modification of software components. RAD involves using pre-built components, reusing existing code, and involving end-users throughout the development process to ensure their needs are met.
One example of RAD is the use of visual programming tools, where developers can drag and drop pre-built components to create the application's user interface. Another example is the Agile development methodology, which follows an iterative approach with frequent feedback and collaboration between developers and stakeholders.
RAD is particularly useful when there is a need for quick development and delivery of software solutions, such as in fast-paced business environments or when addressing rapidly changing user requirements.
