Off-line is a term used to describe a state where a device is not connected to the internet or a network. There are several synonyms for off-line, such as disconnected, offline, secluded, isolated, unconnected, and off the grid. These terms refer to a situation where an electronic device is not connected to a server or network, and therefore cannot access data or information from the internet. Being offline can be temporary or permanent, depending on the reason for disconnection. For example, a device may be temporarily off-line due to a weak signal or an interruption in service, but it can also be deliberately disconnected to avoid distractions or privacy concerns.
