What does the acronym “PoE” stand for in networking terminology?

The acronym "PoE" stands for "Power over Ethernet." This technology allows network cables to carry electrical power alongside data. This is particularly useful in scenarios where it is impractical to run separate power lines to devices such as IP cameras, Wireless Access Points (WAPs), and VoIP phones. By utilizing PoE, devices can receive power and connectivity through a single Ethernet cable, simplifying installation and reducing costs associated with infrastructure.

Power over Ethernet operates through specific standards, such as IEEE 802.3af and IEEE 802.3at, which define how power is delivered over the network. This capability enables network administrators to deploy devices in locations that are not near traditional power outlets, enhancing flexibility in device placement and network design.

Other options, while they incorporate the term "Ethernet," do not accurately describe the function of PoE within networking. Thus, the choice of "Power over Ethernet" as the correct answer highlights the essential nature of PoE technology in modern network environments.
