Glossary

This glossary defines terms and abbreviations used in this manual.
10/100Base-T See Ethernet.
Adapter A device or card that connects a computer, printer, or other peripheral
device to the network or to some other device. An Ethernet adapter
connects a computer to the LAN.
Ad-Hoc Network A temporary local area network connecting AP clients together, usually just
for the duration of the communication session. The clients communicate
directly to each other and not through an established, such as through a
router. Also known as IBSS (Independent Basic Service Set).
Broadband High-speed telecommunication over a wide range of frequencies, typically
256 Kbps or faster. Broadband enables more information to be transmitted
in less time. The most common broadband service types available to
homes and small-offices are cable modem and DSL. Both cable modem
and DSL are much faster than a traditional dial-up Internet connection.
Broadband If you have a cable modem, the cable company from which you subscribe
Provider to high-speed data service. If you have a DSL modem, the telephone
company from which you subscribe to DSL service.
BSS Basic Service Set. A configuration of Access Points that communicate with
each other without resorting any infrastructure. Also known as Ad-Hoc
networks. Also see ESS.
Cable Modem A device enabling a broadband connection to the Internet over cable
television lines. It requires a subscription for high-speed data service from
your local cable provider.
Coaxial Cable A type of wire consisting of a center wire surrounded by insulation and a
(Coax) grounded shield of braided wire traditionally used mainly to carry cable
television signals. The shield minimizes electrical and radio frequency
interference.
DDNS Dynamic Domain Name System enables you to assign a fixed host and
domain name to a dynamic Internet IP address. It is used when you are
hosting your own web server, FTP server, or another server behind the
router.
Default Gateway A designated router that forwards all traffic not addressed to a host on the
local subnet.
DHCP A Dynamic Host Configuration Protocol server dynamically assigns IP
addresses to client hosts on an IP network. DHCP eliminates the need to
manually assign static IP addresses by "leasing" an IP address and subnet
mask to each client. It enables the automatic reuse of unused IP
addresses. The HH1620 can simultaneously be a DHCP client and a
DHCP server:
DMZ A "de-militarized zone" is one or more hosts logically located between a
private LAN and the Internet. A DMZ prevents direct access by outside
users to private data. (The term comes from the geographic buffers located
between some conflicting countries such as North and South Korea.) In a
typical small DMZ configuration, the DMZ host receives requests from
private LAN users to access external web sites and initiates sessions for
these requests. The DMZ host cannot initiate a session back to the private
LAN. Internet users outside the private LAN can access only the DMZ host.
You can use a DMZ to set up a web server or for gaming without exposing
confidential data.
