MAC
Media Access Control. Lower of the two sublayers of the data
link layer defined by the IEEE. The MAC sublayer handles
access to shared media, such as whether token passing or
contention will be used.
MAC address
Standardized data link layer address that is required for every
port or device that connects to a LAN. Other devices in the
network use these addresses to locate specific ports in the
network. and to create and update routing tables and data
NAT
Network Address Translation. Mechanism for reducing the
need for globally unique IP addresses. NAT allows an
organization with addresses that are not globally unique to
connect to the Internet by translating those addresses into
globally routable address space.
Open System
Authentication Open System authentication is a null authentication algorithm.
Any station that requests authentication receives it. If the key
that the station is using is not correct, then further
communication is not possible
Ping
A utility to determine whether a specific IP address is
accessible. It works by sending a packet to the specified
address and waiting for a reply.
PPP
Point-to-Point Protocol. Successor to SLIP that provides router-
to-router and host-to-network connections over synchronous
and asynchronous circuits, designed to work with several
network layer protocols, such as IP, IPX, and ARA. PPP also has
built-in security mechanisms, such as CHAP and PAP.
PPPoE
PPP over Ethernet networks.
RTS
Request To Send is a signal sent from the transmitting station
to the receiving station requesting permission to transmit.
Shared Key
Authentication When Shared Key authentication is enabled, the Access Point /
Router sends a packet to the client. The client uses a secret key
in order to encode the packet and retransmits the encoded
information back to the Access Point / Router. If the packet is
correctly encoded then the client is authenticated
SSID
Service Set Identifier is a unique name shared among all clients
and nodes in a wireless network. The SSID must be identical for
all clients and nodes within a wireless network.
