Which type of web application requires a separate application to be installed before you can use the app?

• A. Client-based web app
• B. Server-based web app
• C. Mobile app
• D. Desktop app

Answer: (A)

A client-based web app requires a separate program to be installed on the user’s device. In this setup, much of the user interface and logic runs in a thick client installed locally, which then talks to a server for data and operations. Because the installed client is needed before you can use the service, it fits the description of needing a separate installation. In contrast, a server-based web app runs on the server and you access it through a browser with little or no local software installation. A mobile app or a desktop app isn’t considered a web app in the same sense, since mobile and desktop apps are typically standalone applications rather than web-based interfaces.
