Q. What is the difference between PoE adapters and ethernet?

PoE adapters are called PoE injectors and they are different from an ethernet. PoE adapter is a device that provides power to any of the networked devices. The Ethernet is a structure for linking many of the computer systems and components together in order to create a LAN or a local area network. This is generally achieved by use of various network protocols that regulate the transfer of data in order to ensure that there is no data transmission overlap. Ethernet generally requires ethernet cables and PoE uses the ethernet cables for data transfer.
