LAN - A local area network (LAN) is a group of computers and asso-

ciated devices that share a common communications line and

typically share the resources of a single processor or server

within a small geographic area (for example,within an office

building).

MAC Address - Short for Media Access Control address,a hard-

ware address that uniquely identifies each node of a network.In

IEEE 802 networks,the Data Link Control (DLC) layer of the OSI

Reference Model is divided into two sublayers:the Logical Link

Control (LLC) layer and the Media Access Control (MAC) layer.

The MAC layer interfaces directly with the network media.

Consequently, each different type of network media requires a

different MAC layer.

Ping (Packet INternet Groper) - 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.PING is used pri-

marily to troubleshoot Internet connections.

Preamble Type- The preamble defines the length of the CRC

block for communication between the Access Point and a roam-

ing Network Card.(High network traffic areas should use the

shorter preamble type.) All wireless points (nodes) on your net-

work should use the same preamble type.

RJ-45 - Short for Registered Jack-45,an eight-wire connector

used commonly to connect computers into local-area networks

(LAN),especially Ethernets.RJ-45 connectors look similar to the

RJ-11 connectors used for connecting telephone equipment,

only wider.

RTS Threshold- This value should remain at its default setting of

2,432.Should you encounter inconsistent data flow,only minor

modifications are recommended.

Roaming – Is the ability to move from one AP coverage area to

another without interruption in service or loss in connectivity.
