   The original PoE standard, IEEE 802.3af-2003, [1] now known as Type 1, provides up to 15.4 W of DC power (minimum 44 V DC and 350 mA) [2] [3] on each port. [4] Only 12.95 W is guaranteed to be available at the powered device as some power dissipates in the cable.

4. Medium-dependent interface - Wikipedia

   These are referred to as MDI and MDI-X (medium-dependent interface crossover). When connecting an MDI port to an MDI-X port, a straight-through cable is used, while to connect two MDI ports or two MDI-X ports, a crossover cable must be used. Conventionally, MDI is used on end devices and routers while MDI-X is used on hubs and switches.

5. Network switch - Wikipedia

   In the extreme case (i.e. micro-segmentation), each device is directly connected to a switch port dedicated to the device. In contrast to an Ethernet hub, there is a separate collision domain on each switch port. This allows computers to have dedicated bandwidth on point-to-point connections to the network and also to run in full-duplex mode.
