PoE stands for Power over Ethernet, which is a technology that allows electrical power to be transmitted along with data over standard Ethernet cabling. This capability eliminates the need for separate power sources for devices such as IP cameras, VoIP phones, and wireless access points by allowing these devices to receive both power and data through a single cable.

Power over Ethernet operates by using two methods: IEEE 802.3af (PoE) and IEEE 802.3at (PoE+), which provide different power levels to connected devices. This simplifies installation and reduces costs, as it minimizes the amount of wiring needed and allows for more flexible placement of powered devices since they do not have to be located near electrical outlets.

The other options do not accurately reflect established networking terminology. The concept of Power over Ethernet is critical in modern networking environments, especially as the demand for networked devices continues to grow. Understanding PoE is fundamental for anyone involved in deploying or managing network infrastructure.
