Wake on lan (WOL)
      Wake on lan is an ethernet standard that enables you to turn on a remote computer by sending a wake on lan magic packet to that computer (without physicaly turn on power button on CPU). It works on the Ethernet MAC address. You must know the Mac address of the remote computer, and also WOL must be enabled in BIOS settings (can found in power management settings of BIOS). Also the remote computers Motherboard and NIC card must support Ethernet WOL feature.
