: Glossary
A
Access Point
-
An internetworking device that seamlessly connects wired and wireless networks
together.
Ad-Hoc Mode
-
A client setting that provides independent peer to peer connectivity in a wireless
LAN. An alterative setup is where PCs communicate with each other through an access point.
B
Bandwidth
- The transmission capacity of a given facility, in terms of how much data the facility
can transmit in a fixed amount of time; expressed in bits per second (bps).
Bit
- A binary digit. The value - 0 or 1-used in the binary numbering system. Also, the smallest
form of data.
BSS
-
Stands for
B
asic
S
ervice
S
et. An Access Point associated with several stations.
D
Default Gateway
- The routing device used to forward all traffic that is not addressed to a station
within the local subnet.
DHCP server and client
-
DHCP stands for Dynamic Host Configuration Protocol. This protocol
is designed to automatically load parameters for the TCP/IP network, including the IP address,
host name, domain name, netmask, default gateway, and name server address. The machine that
provides this service is called the DHCP server, and its client computers are called DHCP clients.
If client computers support DHCP, a TCP/IP configuration is not needed on each client computer.
Diversity Antennas
- An intelligent system of two antennas that continually senses incoming
radio signals and automatically selects the antenna best positioned to receive it.
Domain
- A subnetwork comprised of a group of clients and servers under the control of one
security database. Dividing LANs into domains improves performance and security.
Driver
- A workstation or server software module that provides an interface between a network
interface card and the upper-layer protocol software running in the computer; it is designed for a
specific NIC, and is installed during the initial installation of a network compatible client or
server operating system.
DSSS (Direct-Sequencing Spread-Spectrum)
- DSSS operate over the radio airwaves in the
unlicensed ISM band (industrial, scientific, medical). DSSS uses a radio transmitter to spread data
packets over a fixed range of frequency band.
E
Encryption
- A security method that applies a specific algorithm to data in order to alter the
data's appearance and prevent other devices from reading the information.
