Appendix E: Glossary

The Glossary provides an explanation of terms and acronyms discussed in this user guide.
10BASE-T: IEEE 802.3 specification for 10 Mbps Ethernet over twisted pair wiring.
100BASE-Tx: IEEE 802.3 specification for 100 Mbps Ethernet over twisted pair wiring.
802.11b: IEEE specification for wireless networking at 11 Mbps using direct-sequence spread-spectrum
(DSSS) technology and operating in the unlicensed radio spectrum at 2.4GHz.
802.11g: IEEE specification for wireless networking at 54 Mbps using direct-sequence spread-spectrum
(DSSS) technology and operating in the unlicensed radio spectrum at 2.4GHz.
802.11x: 802.1x defines port-based, network access control used to provide authenticated network access
and automated data encryption key management. The IEEE 802.1x draft standard offers an effective
framework for authenticating and controlling user traffic to a protected network, as well as dynamically
varying encryption keys.
AP: Access Point: A station that transmits and receives data in a WLAN (Wireless Local Area Network). An
access point acts as a bridge for wireless devices into a LAN.
ATM: Asynchronous Transfer Mode: A method of transfer in which data is organized into 53-byte cell units.
ATM cells are processed asynchronously in relation to other cells.
BC: Broadcast: Communication in which a sender transmits to everyone in the network.
BER: Bit Error Rate: Percentage of Bits that contain errors relative to the total number of bits transmitted.
Bridge: A device that connects two networks and decides which network the data should go to.
Bridge Mode: Bridge Mode is used when there is one PC connected to the LAN-side Ethernet or USB port.
IEEE 802.1D method of transport bridging is used to bridge between the WAN (ADSL) side and the LAN
(Ethernet or USB) side, i.e., to store and forward.
CBR: Constant Bit Rate: A constant transfer rate that is ideal for streaming (executing while still downloading)
data, such as audio or video files.
Cell: A unit of transmission in ATM, consisting of a fixed-size frame containing a 5-octet header and a
48-octet payload.
