printed on the cable jacket. Cat 5 cable contains eight conductors, arranged in four twisted pairs, and 
terminated with an RJ45 type connector. In addition, there are restrictions on maximum cable length for both 
10 and 100 Mbits/second networks.

A Certificate Authority is a trusted third-party organization or company that issues digital certificates used 
to create digital signatures and public-private key pairs. The role of the CA in this process is to guarantee 
that the individual granted the unique certificate is, in fact, who he or she claims to be. Usually, this means 
that the CA has an arrangement with a financial institution, such as a credit card company, which provides it 
with information to confirm an individual's claimed identity. CAs are a critical component in data security 
and electronic commerce because they guarantee that the two parties exchanging information are really who 
they claim to be.

An Ethernet protocol specifying how a centralized DHCP server can assign network configuration 
information to multiple DHCP clients. The assigned information includes IP addresses, DNS addresses, and 
gateway (router) addresses.

Specifying a Default DMZ Server allows you to set up a computer or server that is available to anyone on 
the Internet for services that you haven't defined. There are security issues with doing this, so only do this if 
you'll willing to risk open access. 

Short for Domain Name System (or Service), an Internet service that translates domain names into IP 
addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really 
based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name 
into the corresponding IP address. For example, the domain name www.example.com might translate to 
198.105.232.4. The DNS system is, in fact, its own network. If one DNS server doesn't know how to 
translate a particular domain name, it asks another one, and so on, until the correct IP address is returned. 

A descriptive name for an address or group of addresses on the Internet. Domain names are of the form of a 
registered entity name plus one of a number of predefined top level suffixes such as .com, .edu, .uk, etc. For 
example, in the address mail.NETGEAR.com, mail is a server name and NETGEAR.com is the domain.

Short for digital subscriber line, but is commonly used in reference to the asymmetric version of this 
technology (ADSL) that allows data to be sent over existing copper telephone lines at data rates of from 1.5
