Researchers working at the National Institute of Standards and Technology (NIST) have demonstrated for the first time the existence of a key magnetic—as opposed to electronic—property of specially built semiconductor devices. This discovery raises hopes for even smaller and faster gadgets that could result from magnetic data storage in a semiconductor material, which could then quickly process the data through built-in logic circuits controlled by electric fields.

Now that power via media-dependent interface (MDI) was added to the IEEE 802.3af Standard, data terminal equipment (DTE) can receive power over existing data transmission cables. The IEEE 802.3af Standard defines the requirements associated with providing and receiving power over the existing cabling. The power sourcing equipment (PSE) provides the power on the cable, and the powered device (PD) receives the power.
