GLOSSARY 131
DNS Server Address DNS stands for Domain Name System, which allows Internet host computers to have a domain name (such as 3com.com) and one or more IP addresses (such as 192.34.45.8). A DNS server keeps a database of host computers and their respective domain names and IP addresses, so that when a domain name is requested (as in typing “3com.com” into your Internet browser), the user is sent to the proper IP address. The DNS server address used by the computers on your home network is the location of the DNS server your ISP has assigned.
DSL modem DSL stands for digital subscriber line. A DSL modem uses your existing phone lines to send and receive data at high speeds.

ESSID Extended Service Set Identifier. The ESSID is a unique identifier for your wireless network. You must have the same ESSID entered into the Router and each of it's wireless clients.

Firewall Electronic protection that prevents anyone outside of your network from seeing your files or damaging your computers.
Full Duplex A system that allows packets to be transmitted and received at the same time and, in effect, doubles the potential throughput of a link.
Half Duplex A system that allows packets to transmitted and received, but not at the same time. Contrast with full duplex.
