Glossary
Access Point
An interview networking device that seamlessly connects wired and wireless networks
Authentication
Authentication refers to the verification of a transmitted message’s integrity.
DMZ
DMZ (DeMilitarized Zone) is a part of a 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.
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.
DNS
DNS stands for Domain Name System. DNS converts machine names to the IP addresses that all
machines on the net have. It translates from name to address and from address to name.
Domain Name
The domain name typically refers to an Internet site address.
DTIM
DTIM (Delivery Traffic Indication Message) provides client stations with information on the next
opportunity to monitor for broadcast or multicast messages.
Filter
Filters are schemes which only allow specified data to be transmitted. For example, the AP can filter
specific IP addresses so that users cannot connect to those addresses.
Firewall
Firewalls are methods used to keep networks secure from malicious intruders and unauthorized access.
Firewalls use filters to prevent unwanted packets from being transmitted. Firewalls are typically used
to provide secure access to the Internet while keeping an organization's public Web server separate
from the internal LAN.
Firmware
Firmware refers to memory chips that retain their content without electrical power (for example, BIOS
ROM). The AP firmware stores settings made in the interface.
Fragmentation
Refers to the breaking up of data packets during transmission.
