Appendix D: Glossary

The Glossary provides an explanation of terms and acronyms discussed in this user guide.
10BASE-T: IEEE 802.3 specification for 10 Mbps Ethernet over twisted pair wiring.
100BASE-Tx: IEEE 802.3 specification for 100 Mbps Ethernet over twisted pair wiring.
1000BASE-Tx: IEEE 802.3 specification for 1000 Mbps Ethernet over twisted pair wiring.
802.11b: IEEE specification for wireless networking at 11 Mbps using direct-sequence
spread-spectrum (DSSS) technology and operating in the unlicensed radio spectrum at 2.4GHz.
802.11n: IEEE specification for wireless networking at 54 Mbps using direct-sequence
spread-spectrum (DSSS) technology and operating in the unlicensed radio spectrum at 2.4GHz.
802.11x: 802.1x defines port-based, network access control used to provide authenticated network
access and automated data encryption key management. The IEEE 802.1x draft standard offers an
effective framework for authenticating and controlling user traffic to a protected network, as well as
dynamically varying encryption keys.
AP: Access Point: A station that transmits and receives data in a WLAN (Wireless Local Area Network).
An access point acts as a bridge for wireless devices into a LAN.
BC: Broadcast: Communication in which a sender transmits to everyone in the network.
DHCP: Dynamic Host Configuration Protocol: A communications protocol that allows network
administrators to manage and assign IP addresses to computers within the network. DHCP provides a
unique address to a computer in the network which enables it to connect to the Internet through
Internet Protocol (IP). DHCP can lease and IP address or provide a permanent static address to those
computers who need it (servers, etc.).
DMZ: Demilitarized Zone: A computer Host or network that acts as a neutral zone between a private
network and a public network. A DMZ prevents users outside of the private network from getting direct
access to a server or any computer within the private network. The outside user sends requests to the
DMZ, and the DMZ initiates sessions in the public network based on these requests. A DMZ cannot
initiate a session in the private network, it can only forward packets to the private network as they are
requested.
DNS: Domain Name System: A method to locate and translate Domain Names into Internet Protocol
(IP) addresses, where a Domain Name is a simple and meaningful name for an Internet address.
Firewall: A firewall is a method of implementing common as well as user defined security policies in an
effort to keep intruders out. Firewalls work by analyzing and filtering out IP packets that violate a set of
rules defined by the firewall administrator. The firewall is located at the point of entry for the network.
