duplicate packets

E

EAP

EAP-FAST

Ethernet

Direct-sequence spread spectrum. A type of spread spectrum radio transmission that spreads its signal continuously over a wide frequency band.

Packets that were received twice because an acknowledgement got lost and the sender retransmitted the packet.

Extensible Authentication Protocol. EAP is the protocol for the optional IEEE 802.1X wireless LAN security feature. An access point that supports 802.1X and EAP acts as the interface between a wireless client and an authentication server, such as a Remote Authentication Dial-In User Service (RADIUS) server, to which the access point communicates over the wired network.

Extensible Authentication Protocol - Flexible Authentication via Secure Tunneling. An 802.1X authentication type that is available for use with Windows 2000 and XP. With EAP-FAST, a username, password, and PAC are used by the client adapter to perform mutual authentication with the RADIUS server through an access point.

The most widely used wired local area network. Ethernet uses carrier sense multiple access (CSMA) to enable computers to share a network and operates at 10, 100, or 1000 megabits per second (Mbps), depending on the physical layer used.

F

file server	A repository for files so that a local area network can share files, mail, and programs.
fragmentation	The size at which packets are fragmented and transmitted a piece at a time instead of all at once. The
threshold	setting must be within the range of 64 to 2312 bytes.
full duplex	A means of communication whereby each node receives and transmits simultaneously (two-way). See
	also half duplex.

G

gateway	A device that connects two otherwise incompatible networks together.
GHz	Gigahertz. One billion cycles per second. A unit of measure for frequency.

H

half duplex

hexadecimal

A means of communication whereby each node receives and transmits in turn (one-way). See also full duplex.

A set of characters consisting of ten numbers and six letters (0-9, A-F, and a-f).
