The correct statement about web-based applications is:
**You must have an internet connection to use a web application.**
Web applications typically run on a server and require an internet connection to access them through a web browser. The other statements are incorrect for the following reasons:
- **Web applications process information locally on your computer**: This is not true as web applications generally process information on the server side rather than locally.
- **The web version of a desktop application has all the same features as the desktop version**: This is often not the case, as web applications may have limited features compared to their desktop counterparts due to platform differences.
- **Before you can use a web application, you must install it on your computer**: This is incorrect since web applications do not require installation; they can be accessed directly via a web browser.
