10 Gb media-independent interface (XGMII): The interface between the media-dependent and -independent parts of the Ethernet protocol stack.
10 Gigabit Ethernet (10 GigE): The emerging IEEE standard for Ethernet operation at 10 Gbps.
10 Gigabit Ethernet Alliance (10 GEA): An organization promoting the rapid deployment of 10 GigE.
802.2: Sets standards at the logical link control sublayer of the data link layer.
802.3: CSMA/CD (Ethernet) standards that apply at the PHY and MAC sublayer.
8B/10B encoding: An encoding scheme at the GigE physical coding sublayer adopted from the FC-1 Fibre Channel specification. It transmits 8 bits as a 10-bit code group.

Active hub: A multiport device that amplifies LAN transmission signals.
Add/drop multiplexer (ADM): A multiplexer capable of extracting or inserting lower-rate signals from higher-rate multiplexed signals without completely demultiplexing the signal.
American National Standards Institute (ANSI): The coordinating body for voluntary standards groups within the United States. ANSI is a member of the International Organization for Standardization (ISO).
