APPENDIX C 
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.
