2. Power-line communication - Wikipedia

   en.wikipedia.org/wiki/Power-line_communication

   Power line adapter. Power-line communication (PLC) is the carrying of data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers. The line that does so is known as a power-line carrier. In the past, power lines were solely used for transmitting electricity. However, with ...

   Advocates of PoE expect PoE to become a global long-term DC power cabling standard and replace a multiplicity of individual AC adapters, which cannot be easily centrally managed. [23] Critics of this approach argue that PoE is inherently less efficient than AC power due to the lower voltage, and this is made worse by the thin conductors of ...

6. Adapter - Wikipedia

   en.wikipedia.org/wiki/Adapter

   An adapter or adaptor [1] is a device that converts attributes of one electrical device or system to those of an otherwise incompatible device or system. Some modify power or signal attributes, while others merely adapt the physical form of one connector to another.

7. Universal powerline bus - Wikipedia
