What are Multi Page Applications?

The Multiple-Page Applications operate in a traditional way. Every change like displaying the data or submitting the data back to server requests rendering a new page from the server in the browser. These applications are large, bigger than SPA. Due to the huge amount of content, these applications have many levels of User Interfaces. Because of AJAX, we do not have to worry that, big and complex applications have to transfer a lot of data between server and browser. That solution improves and it allows to refresh only particular parts of the application. On the other hand, it adds more complexity and it is more difficult to develop than a single-page application.
