100BaseFX |
A fast ethernet implementation over multimode fiber-optic cabling. The maximum segment length is 412 meters |
|
|
100BaseT4 |
A 100-Mbps Fast Ethernet implementation that uses four pairs of either Category 3, 4, or 5 UTP cable. The maximum segment length is 100 meters |
|
|
100BaseTX |
A Fast Ethernet implementation that uses two pairs of either Category 5 UTP or STP. 100BaseTX operates at 100-Mbps with a maximum segment distance of 100 meters |
|
|

An IEEE 802.3z Gigabit Ethernet implementation that uses single-mode fiber to achieve 1000-Mbps |
|
|
100BaseSX |
An IEEE 802.3z Gigabit Ethernet implementation that uses multimode fiber to achieve 1000-Mbps |
|
|
100BaseT |
An IEEE 802.3ab Gigabit Ethernet implementation that uses all four pairs of Category 5 or better UTP cable to achieve 1000-Mbps |
|
|
Active Hub |
A device that connects multiple nodes and/or networks, is connected to external power, and repeats and regenerates signals on a network |
|
|
Ad Hoc Mode |
A wireless mode where client devices connect directly to each other without an access point |
|
|
Amplifier |
A device used to boost analog signals on a broadband network |
|
|
Analog |
A method of signal transmission on broadband networks |
|
|
Attenuation |
The natural degradation of a transmitted signal over distance |
|
|
Back off Period |
A random time interval used after a collision has been detected on an Ethernet network. Use of a back off period minimizes the likelihood of another collision |
|
|
Bandwidth |
The available capacity of the network. The greater the network bandwidth, the greater the speed in data transfer |
|
|
Basic Service Set (BSS) |
A wireless network with only one access point connected to a switch |
|
|
Bridge |
A device that operates at the Data Link layer, used to filter traffic between network segments by evaluating the MAC adress of packets that are sent to it |
|
|
Broadcast |
A frame meant for the entire network |
|
|
Broadcast Domain |
A group of network devices that will receive LAN broadcast traffic from each other |
|
|
Broadcast Storm |
Excessive broadcast messages to every host on the network, launched by multiple computers, usually triggered by some error condition on the network |
|
|
Brouter |
A device that functions as a bridge for non-routable protocols, and a router for routable protocols. The brouter operates at both the Data Link and Network layers |
|
|
Carrier Sense Multiple Access with Collision Detection (CSMA/CD) |
An acess method specified by the IEEE Ethernet 802.3 standard. In this method, a node will listen to see if the line is clear and then, if the line is clear, send data. Two nodes may still send at the same time and cause a collision, in which case the two nodes will then perform the back off algorithm |
|
|
Carrier Signal |
A transmitted electromagnetic pulse or wave on the network wire that indicates a transmission is in progress |
|
|
Collision Domain |
In Ethernet networking, a single segment on a network. Any station on the same physical segment or separated by a repeater is in the same collision domain. Bridges, routers, and switches can separate collision domains |
|
|
Contention |
The condition that occurs when computers on a network must share the available capacity of the network wire with other computera |
|
|
Fast Ethernet |
Defined in IEEE 802.3u, and includes any of the following 100-Mbps Ethernet LAN technologies: 100BaseT4, 100BaseTX, or 100BaseFX |
|
|
Extended Service Set |
A wireless network with multiple access points connected to switches. The acess points are typically configured with the same network name (SSID) to facilitate roaming. |
|
|
Extensible Authentication Protocol (EAP) |
Works with 802.1x to carry the authentication information between the user, the acess point, and the security server |
|
|
Full-Duplex |
A connection that allows communication in two directions at once; common telephone connections are typically full-duplex because people can talk and listen at the same time |
|
|
Gateway |
A combination of hardware and software that translates between different protocols on the network |
|
|
Gigabit Ethernet |
Includes IEEE 802.3z and IEEE 802.3ab, which allows for speeds up to 1000 Mbps |
|
|
10 Gigabit Ethernet (10GbE or 10 GigE) |
A standard ten times faster than gigabit Ethernet that is always implemented as full duplex |
|
|
Half-Duplex |
A connection that allows communication in two directions, but not simultaneously; the circuit can be used for sending or receiving bits in only one direction at a time |
|
|
Hub |
An active or passive device that connects network segments. Passive hubs are connection points; active hubs repeat and regenerate signals |
