Question

What is difference between web app and website?

Answer 1

In pretty simple terms, you could put it like this.
Web application in its definition is an application that has extensive support and connectivity to a server side API. We can take Android applications for example. Most of the client-side applications are given a possibility to utilize most of the hardware through the OS that the software is actually running on, and yet have the privilege to query their own databases for more information or send relevant information to the database.
Website in other terms, just doesn't offer this touch with the hardware of the platform, but it's mostly just represented by the HTML language to provide the input output operations. With some operations obviously that are left for the Javascript to figure out. The upside to this though, is that the functionality of websites can be used to create very lightweight user interfaces for the users, that are responsive and fast for the benefit of the user. This completely blocks out the offline functionality though, unless the data is static, like literature.
