What Does HomePlug Mean?

Techopedia Explains HomePlug

First introduced in June 2001, HomePlug is a specification standard used in testing and standardization of hardware used for communication of two or more devices. The HomePlug Powerline Alliance is a joint venture of a number of device manufacturers that oversees the HomePlug standard. HomePlug has revolutionized the way that devices are able to connect by Ethernet network. The HomePlug hardware can simply be plugged into any existing power socket in a building, and all devices connected to it can have access to the data as if they were plugged into a standard Ethernet connection.
