Offline Mode refers to a state in which an electronic device or software is able to function without being connected to the internet. This means that the device can still be used, but it will not have access to online content or services such as browsing the web, checking emails, social media, streaming videos or music, and online gaming. Offline Mode typically allows users to continue using certain features of an app or program even when they are disconnected from the internet. This can be useful in situations where there is no internet connection available, such as on a plane, train, or in remote areas with limited connectivity.
