Access Point
Access points are the contact points (wireless routers and transmitters) in a wireless LAN that are
connected to an Ethernet hub or server. Users can roam within the range of access points and their
wireless device connections are passed from one access point to the next.
Administrator
The network administrator is the person who manages the LAN. The administrator's tasks include
ensuring network security, keeping software, hardware, and firmware up-to-date, and keeping track of
network activity. Your router Administrator is the person in control of access to your router. The system
starts out with all users as administrators.
Authentication
Authentication refers to the verification of a transmitted message's integrity.
Beacon Interval
Refers to the interval between packets sent by routers for the purposes of synchronizing wireless LANs.
Broadband
Usually refers to Internet connections that provide faster data transfer than standard dial-up connections
(cable modem, DSL, T-1, etc.)
DDNS
Dynamic DNS (Domain Name System).
DHCP
DHCP (Dynamic Host Configuration Protocol) software automatically assigns IP addresses to client stations
logging onto a TCP/IP network, which eliminates the need to manually assign permanent IP addresses.
DHCP Client
The DHCP client list shows all of the computers attached to your local network. The list shows the host
name of the computer.
DMZ
DMZ (Demilitarized Zone) is a part of an network that is located between a secure LAN and an insecure
WAN. DMZs provide a way for some clients to have unrestricted access to the Internet.
DNS
DNS stands for Domain Name System. DNS converts domain names to the IP addresses that all
machines on the Internet have. It translates from name to address and from address to name.
Domain Name
The domain name is the "readable" version of an Internet site address. A typical domain name has the
form "www.somedomainname.com" or "www.somedomainname.org", etc.
DTIM
DTIM (Delivery Traffic Indication Message) provides client stations with information on the next opportu-
nity to monitor for broadcast or multicast messages.
Filter
Filters only allow specified data to be transmitted or received. For example, the router can filter specific
IP addresses so that users cannot connect to those addresses.
