Responsive and adaptive design is used to create websites that work smoothly across multiple devices. Both design techniques provide a better user interface but have many differences.
The Model-View-Controller (MVC) design pattern is a widely used software architecture pattern in web development. It helps you turn complex software development into three separate components. When a user requests a page from a dynamic website, the server runs the necessary code to generate the content for that page and sends it to the user’s browser.
