Wake Up Your PC Over the Internet

These days you don't need to be sitting in front of a PC to use it considering the countless utilities/services that can provide remote access to a system over the Internet.

If you regularly access a system from afar, you probably leave it on 24/7 to ensure its constant availability. Keeping a system perpetually powered on can be a tremendous waste of energy and money, and as it turns out you don't necessarily have to run a system all day and night in order to guarantee remote access.

Setting a system up for Wake-on-LAN (WoL) will allow it to enter various power-saving modes--standby, hibernation, even a complete shutdown--and still let you rouse the system from its slumber when you needed.
