Extensible Authentication Protocol over Wireless (EAPoW) When EAPoL
messages are encapsulated over 802.11 wireless frames, they are known as
EAPoW.
Fast Ethernet The standard speed of 100 Mbps, coaxial, or twisted pair cable.
File Server A client/server role that allows clients to save data to folders on its
hard drive.
Firewall A device that protects a secure internal network from a public insecure
network. Firewalls have the ability to control the traffic that is sent
from an external network, such as the Internet, to an internal network or
local computer.
Full Duplex A term that refers to data traveling in both directions simultaneously.
Gateway A bridge connecting two dissimilar systems.
Gigabit Ethernet The standard speed of 1 Gbps, twisted-pair or fiber-optic cable.
Half Duplex A term that refers to data traveling both ways, but in only one
direction at a time.
Hardware Loopback Adapter A tool that provides a way to test the ports on a
system without having to connect to an external device.
Hub A device that passes data to other computers or networks. Hubs, or concentrators,
are central devices where network cabling is connected. Multiple
cables connect into the hub, providing a method for data to be passed from
one cable to another.
Integrated Services Digital Network (ISDN) A system of digital telephone connections
that enables data to be transmitted simultaneously end to end.
Intrusion Detection System (IDS) A device designed to inspect and detect the
kinds of traffic or network behavior patterns that match known attack signatures
or that suggest potential unrecognized attacks may be incipient or in
progress.
Load Balancer A device that will distribute connection load between multiple
devices in your environment that are serving the same function.
Local Connector (LC) A connector used with fiber-optic cabling.
Logical Link Control (LLC) A sublayer of the data link layer of the OSI model.
The LLC provides the logic for the data link layer.
Man-in-the-Middle Through Rogue Access Points Interception of network
communications through deployment of an access point (AP) with enough
strength so that the end users may not be able to tell which AP is the authorized
one that they should be using.
Mechanical Transfer Registered Jack (MTRJ) A connector used with fiber-optic
cabling.
Media Cables or wireless technologies that carry the data across the network.
Media Access Control (MAC) A sublayer of the data link layer of the OSI model.
It provides control for accessing the transmission medium.
