Wake on LAN (WOL), is a technology that turns on a computer without you being physically present at the computer. A WOL command broadcasts a specially formed network message called a magic packet to all computers on the same network segment as the target computer. Each computer's network card is uniquely identifiable by its Media Access Control (MAC) address. Only the computer that has the target MAC address will respond by signaling the motherboard to power on the computer. The WOL command-line utility by Matcode is one of many utilities that can send a WOL command.
