Remote Wakeup is a feature that allows a device, such as a computer or a networked printer, to be turned on or awakened from a low-power state remotely. This is typically done over a network, enabling users to access their devices without needing to be physically present. This technology is often used in IT management and home automation systems, allowing for convenient access and control. It can help save energy by keeping devices in a low-power state when not in use, while still providing the ability to wake them up when needed.
