25. What is the difference between responsive and adaptable design?

Ans: The responsive design adheres to the flexibility idea. It adjusts to the size of the screen and provides the best viewing experience for a website regardless of the device used to view it. Responsive websites use CSS media queries and flexible grids to adjust styles based on device parameters such as display type, width, and height.

Adaptive design uses static designs rather than adaptable layouts. Its architecture is built on breakpoints that do not respond once loaded. It identifies the device’s kind and other attributes. Then it delivers the functionality and form depending on a specified set of parameters. Both responsive and adaptable designs maximize the user experience across several target devices, and both compensate for various viewport widths, resolutions, and control techniques.

Non-functional requirements, on the other hand, specify how the system should perform its functions.

Non-functional requirements define system behaviour, features, and general characteristics that impact the user experience. 

Non-functional criteria do not affect the system’s essential functioning. Even if the non-functional requirements are not satisfied, the system will continue to work.
