Wake-on-LAN is an Ethernet computer networking standard that allows a computer to be turned on or woken up by a network message
Wake-on-LAN is a protocol intended for waking computers up from a very low power mode in a remote fashion.
Wake-on-LAN is mainly used by system administrators, who perform computer maintenance tasks remotely. The computer receiving the special data packet, which is sometimes referred to as the "Magic Packet", must have a motherboard, network adapter, adapter driver and computer basic input/output system (BIOS) that work with Wake-on-LAN.
The protocol also allows for a supplementary Wake-on-Wireless-LAN ability as well.
