(WOL (Wake on LAN) technology is a technology that can realize remote startup of remote workstation through local area network. No matter how far away the workstation computer is and where it is located, as long as it is in the same local area network, the remote workstation can be enabled at any time, and it is no longer afraid that the power supply of the workstation is turned off (the power socket still needs to be plugged in and turned on).)
