What Does Remote Wake-Up (RWU) Mean?
Remote Wake-Up refers to remotely turning on a networked computer by sending a network message (called a magic packet) that contains the MAC address of the computer. On receipt, the computer initiates the system wake-up. The computer receiving the magic packet does not need to be left “on,” as was the case before Remote Wake-Up became available; so IP personnel no longer have to manually turn “on” networked computers, or remind employees to do so, before remotely checking, configuring, installing software or other tasks. This feature is included in Intel’s Wired for Management (WfM) network specification.
Techopedia Explains Remote Wake-Up (RWU)
Remote Wake-Up is independent of the operating system, or network interface card (NIC), used by the computer. Support for this feature is implemented on the motherboard (in the BIOS) along with the network interface or firmware. However, some operating systems can control the operation with hardware drivers.
