Wake on LAN (WoL) it is a networking feature that IT professionals have been using for years. WoL allows you to remotely wake up a remote computer by means of a “magic” data packet sent from another PC on the network.

The remote PC “listens” for the data packet while in sleep or hibernation mode. If the packet is detected, your PC wakes up. This allows easier access to other Windows machines over a network, which means that you do not need to physically touch the other PC to wake it up and start using it.
