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
primarily to troubleshoot Internet connections.
RJ-45 - Short for Registered Jack-45,an eight-wire connector
used commonly to connect computers into local-area net-
works (LAN), especially Ethernets. RJ-45 connectors look similar
to the RJ-11 connectors used for connecting telephone equip-
ment,only wider.
Roaming – Is the ability to move from one AP coverage area to
another without interruption in service or loss in connectivity.
Static IP Address - A permanent IP address that is assigned to
a node in a TCP/IP network.
Subnet Mask - The method used for splitting IP networks into
a series of subgroups,or subnets. The mask is a binary pattern
that is matched up with the IP address to turn part of the host
ID address field into a field for subnets.
TCP (Transmission Control Protocol) - TCP is one of the main
protocols in TCP/IP networks.Whereas the IP protocol deals
only with packets,TCP enables two hosts to establish a connec-
tion and exchange streams of data.
