Wake on LAN is a procedure in which a signal is sent by a remote PC to another computer on the same network which causes the computer to power on. Wake on LAN is useful for starting a computer remotely in order to remotely access the computer, whether it be to retrieve office files or do work from a distant location. Sending a Wake on LAN command is done by using a type of program called Magic Packet Utility. These programs send a Wake signal through a network to a specific computer address, or MAC address.
