The IEEE 802.3af Power over Ethernet (PoE) standard specifies a more elaborate power negotiation scheme than powered USB. It operates at 48 V DC and can supply more power (up to 12.95 W, PoE+ 25.5 W) over a cable up to 100 meters compared to USB 2.0, which provides 2.5 W with a maximum cable length of 5 meters. This has made PoE popular for VoIP telephones, security cameras, wireless access points and other networked devices within buildings. However, USB is cheaper than PoE provided that the distance is short, and power demand is low.

Different societies apply differing criteria regarding who is classified as "black", and these social constructs have also changed over time. In a number of countries, societal variables affect classification as much as skin color, and the social criteria for "blackness" vary. For example, in North America the term black people is not necessarily an indicator of skin color or majority ethnic ancestry, but it is instead a socially based racial classification related to being African American, with a family history associated with institutionalized slavery. In South Africa and Latin America, for instance, mixed-race people are generally not classified as "black." In South Pacific regions such as Australia and Melanesia, European colonists applied the term "black" or it was used by populations with different histories and ethnic origin.
