What type of application allows users to work even when a network connection is unavailable?

An offline web application is specifically designed to function without a network connection, allowing users to access and interact with the application’s features and data even when they are offline. This is achieved through the use of various technologies and strategies, such as service workers and caching, which store necessary files and data on the user's device.

For example, an offline web application can enable users to input data, view previously accessed information, and perform tasks without needing to connect to a server. Once the connection is restored, any changes made can be synchronized with the server. This capability is particularly important in scenarios where reliable internet access is not guaranteed.

In contrast, static web applications do not have interactivity or the ability to update content dynamically; they are primarily composed of fixed content. Dynamic web applications rely on server-side processing and require an active network connection to function because they pull data in real time from a server. Responsive web applications are designed to adapt their layout and functionality based on different devices and screen sizes but do not address the need for offline capability. Thus, the offline web application stands out for its unique ability to operate independently of a network connection.
