10BASE-T

An IEEE 802.3 Ethernet standard that has a maximum segment length of 100m and has a 10Mbps data transmission speed. 10BASE-T can use Category 3, 4, or 5 unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cables for connectivity.



802.11a

An IEEE wireless networking standard released in 1999 that uses the 5GHz frequency range. 802.11a clients can theoretically transmit at a maximum speed of 54Mbps.



802.11b

An IEEE wireless networking standard released in 1999 that uses the 2.4GHz frequency range. 802.11b clients can theoretically transmit at a maximum speed of 11Mbps.



802.11g

An IEEE wireless networking standard released in 2003 that uses the 2.4GHz frequency range. 802.11g clients can theoretically transmit at a maximum speed of 54Mbps. This standard is backward-compatible with 802.11b clients.



802.11n

A predraft standard for wireless networking that uses Multiple Input, Multiple Output (MIMO) signals to achieve higher throughput. Current predraft equipment uses the 2.4GHz frequency range.



802.1q

An IEEE frame-tagging method over trunk ports that insert the 4-byte VLAN identifier inside the original Ethernet frame.



802.1x
