The 10 Mbps baseband Ethernet specification that uses two pairs of twisted-pair cabling
(Category 3 or 5): one pair for transmitting data and the other for receiving data.
The IEEE standard that specifies Wireless LAN Medium Access Control (MAC) and Physical
Layer (PHY) specifications.
The IEEE standard that specifies Higher-Speed Physical Layer Extension in the 2.4 GHz
Band for 5.5 and 11 megabit per second wireless LANs.
The IEEE standard that specifies carrier sense media access control and physical layer
specifications for Ethernet LANs.
The prevention of unauthorized usage of resources.
Any entity that has station functionality and provides access to the distribution services, via
the wireless medium (WM) for associated stations.
Advanced analog mobile service. Uses a 50 MHz segment of the 800 MHz band to provide
832 analog channels. Two service providers are each assigned one half of the channels in each
service area. Analog cellular systems that are similar to AMPs but not compatible include
Total Access Communications System (TACS) in the United Kingdom, China and other
countries, and Nordic Mobile Telephone (NMT) in the Scandinavian countries.
Address Resolution Protocol is a protocol for mapping an Internet Protocol address (IP
address) to a physical machine address that is recognized in the local network.
The service used to establish the identity of one station as a member of the set of stations
authorized to associate with another station.
Proof that the information came from the person or location that reportedly sent it. One
example of authenticating software is through digital signatures.
A deliberately planned security breach in a program. Back doors allow special access to a
computer or program. Sometimes back doors can be exploited and allow a cracker
unauthorized access to data.
A high-speed line or series of connections that forms a major pathway within a network.
BackOrifice is a remote administration tool which allows a user to control a computer across a
TCP/IP connection using a simple console or GUI application. BackOrifice is a potentially
disastrous Trojan horse since it can provide the user unlimited access to a system.
This is the capacity on a link usually measured in bits-per-second (bps).
(Binary Digit) – A single digit number in base-2, in other words, either a one or a zero. The
smallest unit of computerized data.
A device used to connect LANs by forwarding packets across connections at the Media
Access Control (MAC) layer.
Refers to telecommunication that provides multiple channels of data over a single
