Class of Service

traffic gets faster treatment during times of switch congestion

DHCP

See “Dynamic Host Configuration Protocol.”

DNS

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.

Domain Name

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, and so

on. For example, in the address mail.NETGEAR.com, mail is a server name and NETGEAR.com is the

domain.

DoS

A hacker attack designed to prevent your computer or network from operating or communicating.

DSL

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

to 9 Mbps when receiving data (known as the downstream rate) and from 16 to 640 Kbps when sending data

(known as the upstream rate).

ADSL requires a special ADSL modem. ADSL is growing in popularity as more areas around the world

gain access.

DSLAM

DSL Access Multiplexor. The piece of equipment at the telephone company central office that provides the

ADSL signal.
